(1) could you try setting ahc_pci_prefer_io in ahc_pci.c to 1?
This will tell the ahc driver to prefer I/O space, like it used
to. (There were no other significant changes to the driver, so
that _reall_ should be it. 8-)
(2) I'll send you a set of diffs under a seperate cover, which should
fix the problem 'for real'.
The problem is that apparently there are some x86 laptop docking
stations which don't map the memory spaces of PCI devices in the
docking stations. On the other hand, on the Alpha, the console
firmware apparently doesn't map I/O spaces behind PPBs...
