Re: ACPI orinoco_cs problem

I have ISA support compiled in my ACPI kernel so that was not the
problem.

After playing with my Orinoco card for a while, I found that the card was using
IRQ 7. The intermitent "RequestIRQ: Resource in use" problem went away for me
when I removed the "exclude irq 7" line from /etc/pcmcia/config.opts (the
default in Redhat 9 Shrike). I don't understand completely why this solution
worked since the RequestIRQ code in the kernel seems to look for any unused IRQ
but it seems that the orinoco/pcmcia subsystem only allocates IRQ 7 correctly.
