Subject: [PATCH] clgenfb

Hi Jeff,

thanks for clgenfb, the fb driver for cirrus logic chips!
It made the PowerStorm in my Digital PWS more useable.
I can run XF86 fbdev on top of it; I will replace the VGA ASAP though.

Some hints for people:
I had to use -accel false -vyres -1 to get it sort of stable.

Still, in text-mode apps that scroll windows like jed, it occasionally
crashes the machine :-(
XFree86 fbdev (4.1.0) runs perfeclty though, XFree86 cirrus (4.1.0) produces
distorted output.

I have a patch for you:
* Memory detection was wrong here. I just have 512k, which clgenfb does not
seem to be prepared for. I had another look at XFree86 sources to fix it.
Now it works correctly.
* I added a 800x600 mode and tweaked the timings to more reasonable values:
You always want to have short right/bottom shoulder, medium length sync and
relatively long left/top shoulder to help monitors with syncing.

Please apply,
--
