Problems for IBM x440 in 2.6.16-rc4-mm1 and -mm2 (PCI?)

["Martin J. Bligh" <mbligh@mbligh.org>]

OK, mainline is fine, but -mm won't boot:

mainline boot log:

(-git7)

-mm boot log:

It seems to find no PCI devices at all, and I note that when they first
seem to diverge, we get:

PCI: Probing PCI hardware
PCI quirk: region 0440-044f claimed by vt82c686 SMB
PCI->APIC IRQ transform: 0000:00:03.0[A] -> IRQ 39

PCI->APIC IRQ transform: 0000:00:05.3[D] -> IRQ 47
Setting up standard PCI resources
