  I had to look to the windows cardbus device properties to get it work, 
but i think that by playing with some values you can get it working too 
without needing that crappy OS.

   My  Excuse: The reason i looked into windows whas that i was setting 
up  a laptop whith the host_ap module support and i needed it working 
for giving a wireless talk and  had no time to play. :-)

    I can only give you this link where the problem is referenced and 
have some instructions to guess wich memory addresses to reserve for the 
cardbus.
  http://pcmcia-cs.sourceforge.net/ftp/doc/PCMCIA-HOWTO-3.html#ss3.5

    No. I think kernel does not change anything. Maybe is that the 
kernel fits a region of memory originally reserved for the cardbus as is 
defined in config.opts. Maybe because those new kernel are a few Kb 
bigger than before one's.

    Remembering this thing makes me think that this "issue" is more a 
pcmcia_cs thing than a kernel/driver one.

Hope it helps you or any other developer/list__member here.

PD: Excuse my poor english.
