[PATCH] PCI: use PCI_BIOS 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 PCI_BIOS sometimes reports the last bus wrong, leaving cardbus
non-funcational. previously those system worked fine with direct access.
fix it by chaning the order of the probing, having PCI_BIOS as the last fallback.
