Many thanks for your help Martin,
I have applied the patch to 2.3.40-pre6 but this does not seem to find
the second PCI bus at all, let alone my third/fourth IDE interfaces,
third/fourth PCMCIA slots or my TLAN card. I had the same problem with
2.3.40-pre4 (otherwise unpatched), but 2.3.39 _does_ find all of my PCI
hardware.
I manually applied the changes from your patch to the tlan.c / tlan.h in
2.2.14, but I still received the identical error with that version. I
believe there are quite a few changes in the PCI code in 2.3 so I guess
I should not be surprised :-)
The output of "lspci -v" and "scanpci -v" under 2.3.40-pre6:
