Sure, the trick is finding that fix.
I suggest using git and use 'git bisect' to track down the relevant
patch. See the git documentation for how to do this, it is very simple
to do.
Thanks for the tips. I think this is what I was looking for:

[PATCH] PCI: use PCBIOS as last fallback
there was a change in 2.6.17 which affected the order in which the PCI
access methods are probed. this gives regressions on some machines with
broken BIOS. the problem is that PCBIOS sometimes reports last bus wrong,
leaving cardbus non-funcational. previously those system worked fine with
direct access.
The patch changes the PCI init code to have PCBIOS as last fallback, yet
the PCBIOS code still has to run first to set pcibios_last_bus to the value
reported by the BIOS. this is needed in case legacy PCI probing
(arch/i386/pci/legacy.c) is used to detect peer busses. using direct
access if available fixes the cardbus problems.
This seems to have solved my problem.
