It sounds like 2.2.x is relying on BIOS setup of PCI space even for the

It is likely that 2.3.x needs this as well to some extent, but I can
almost promise you that 2.3.x will behave more sanely when faced with
the lack of BIOS setup...  The 2.3.x kernel PCI code has a ton of
fixup-handling code already, which would be very similar to handling the
completely-lack-of-BIOS case.   It shouldn't be very hard at all to get
the PCI code completely independent of BIOS PCI setup -- if that hasn't
happened already, that is.
