Subject: PCI: use PCI_BIOS as last fallback
From: Daniel Ritz <daniel.ritz-ml@xxxxxxxxxxxxxx>
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-functional. Previously those system worked fine
with direct access. Fix it by chaning the order of the probing, having
PCI_BIOS as the last fallback.
