PCMCIA and ISA relation
I recently got a new Dell Latitude 610 and immediatley dumped W2K and
installed Debian sarge. I compiled my own kernel and it was working
fine. I then needed to make sure my Wireless LAN card worked, and
found that it couldn't get dev resources when inserted. It would load
hermes, which in turn loads the orinoco and orinoco_cs modules.
Here's the error I got in syslog:

After fighting this for a few hours, I got a hunch...in my custom
kernel I did not include ISA Bus support nor ISA Plug-n-Play support.
I didn't think I needed that on what i thought was a purely PCI
system. Well, apparently there is a relationship between the PCMCIA
Cardbus and the ISA bus, because I recompiled my kernel adding the ISA
stuff back and now it works fine.
Perhaps someone can explain this to me, since I don't really get it
beyond the hunch I had.
thanks,
