+	  Software Suspend 2 is the 'new and improved' suspend support. You
+	  can now build it as modules, but be aware that this requires
+	  initrd support (the modules you use in saving the image have to
+	  be loaded in order for you to be able to resume!)
+	  
+	  See the Software Suspend home page (softwaresuspend.berlios.de)

+			  support is currently broken (16 April 2004).

+				tristate '   LZF image compression (Preferred)'
+				---help---
+				  This option enables compression of pages stored during suspending
+				  to disk, using LZF compression. LZF compression is fast and
+				  still achieves a good compression ratio.
+
+				  You probably want to say 'Y'.
+
+			config SOFTWARE_SUSPEND_GZIP_COMPRESSION
+				tristate '   GZIP image Compression (Slow)'
+				depends on SOFTWARE_SUSPEND2_CORE
+				select ZLIB_DEFLATE
+				select ZLIB_INFLATE
+				---help---
+				  This option enables compression of pages stored during Software Suspend
+				  process. Pages are compressed using the zlib library, with a default
+				  setting (in code) of fastest compression (still VERY slow!). If your swap
+				  device is painfully slow compared to your CPU, you might possibly want
+				  this. Then again, you might just want to upgrade your storage (if you
+				  can).
+			  		
+				  Just in case you haven't gotten the hint yet, this option should be off
+				  for most people. If will make your computer take a minute to suspend
+				  when it could take seconds.
+
+			config SOFTWARE_SUSPEND_DEVICE_MAPPER
+				tristate '   Device Mapper support'
+				depends on SOFTWARE_SUSPEND2_CORE && BLK_DEV_DM
+				---help---
+				  This option creates a module which allows Suspend to tell the
+				  device mapper code to allocate enough memory for its work while
+				  suspending. It doesn't do anything else, but without it, dm-crypt
+				  won't work properly.
+
+				  This option should be off for most people.
+
+			comment 'User Interface Options'
+
+			config SOFTWARE_SUSPEND_BOOTSPLASH
+				tristate '  Bootsplash support'
+				depends on SOFTWARE_SUSPEND2_CORE && BOOTSPLASH
+				---help---
+				  This option enables support for Bootsplash (bootsplash.org). Suspend
+				  can set the progress bar value and switch between silent and verbose
+				  modes. (Silent mode is used when the debug level is 0 or 1). 
+				
+			config SOFTWARE_SUSPEND_TEXT_MODE
+				tristate '  Text mode console support'
+				depends on SOFTWARE_SUSPEND2_CORE && VT
+				---help---
+				  This option enables support for a text mode 'nice display'. If you don't
+				  have/want bootsplash support, you probably want this.
+				
+			comment 'General Options'
+
+			config SOFTWARE_SUSPEND_DEFAULT_RESUME2
+				string '   Default resume device name'
+				---help---
+				  You normally need to add a resume2= parameter to your lilo.conf or
+				  equivalent. With this option properly set, the kernel has a value
+				  to default. No damage will be done if the value is invalid.
+
+			config SOFTWARE_SUSPEND_KEEP_IMAGE
+				bool '   Allow Keep Image Mode'
+				---help---
+				  This option allows you to keep and image and reuse it. It is intended
+				  __ONLY__ for use with systems where all filesystems are mounted read-
+				  only (kiosks, for example). To use it, compile this option in and boot
+				  normally. Set the KEEP_IMAGE flag in /proc/software_suspend and suspend.
+				  When you resume, the image will not be removed. You will be unable to turn
+				  off swap partitions (assuming you are using the swap writer), but future
+				  suspends simply do a power-down. The image can be updated using the
+				  kernel command line parameter suspend_act= to turn off the keep image
+				  bit. Keep image mode is a little less user friendly on purpose - it
+				  should not be used without thought!
+
+			comment 'Debugging'
+
+			config SOFTWARE_SUSPEND_DEBUG
+				bool '   Compile in debugging output'
+				---help---
+				  This option enables the inclusion of debugging info in the software
+				  suspend code. Turning it off will reduce the kernel size but make
+				  debugging suspend & resume issues harder to do.
+			
+				  For normal usage, this option can be turned off.
