I had this problem on 2.2.1, and just brought my fix
forward to 2.2.6. I have not tried the stock 2.2.6 sources
with pccard support (the boot floppy worked ok with zp0, but
I needed custom stuff anyway).
Hardware is an IBM Thinkpad 760ED. The resulting kernel doesn't
suspend/resume 100% right, but it basically works ok.
This patch avoids recognizing the 1130 as a pci device; this allowed
(under 2.2.1) it to be probed in isa compatibility mode, where it
acted like the normal bridge chip.
