The complete dmesg is on NetBSD wiki at
        http://wiki.netbsd.org/IBM_Thinkpad_T60

You seem to be right about the BIOS, looking at the PCI_*_FIXUP options,
with a GENERIC (5.0_RC2) kernel from yesterday the differences caused by
the addition of:

options PCI_ADDR_FIXUP
options PCI_BUS_FIXUP
options PCI_INTR_FIXUP_DISABLED

are:

+pci_addr_fixup: 000:31:1 0x8086 0x27df new address 0x00005800
+pci_addr_fixup: 000:31:1 0x8086 0x27df new address 0x00005808
+pci_addr_fixup: 000:31:1 0x8086 0x27df new address 0x00005810
+pci_addr_fixup: 000:31:1 0x8086 0x27df new address 0x0000580c

-pci1 at ppb0 bus 2
+pci1 at ppb0 bus 1

-pci2 at ppb1 bus 3
+pci2 at ppb1 bus 2

-pci3 at ppb2 bus 4
+pci3 at ppb2 bus 3

-pci4 at ppb3 bus 12
+pci4 at ppb3 bus 4

-pci5 at ppb4 bus 21
-pci5: i/o space enabled
+pci5 at ppb4 bus 5
+pci5: i/o space, memory space enabled

-cbb0: can't map socket base address 0xe4300000
-cbb0: can't map socket base address 0xc0a07496: io mode

-cardbus0 at cardslot0: bus 22
+cardbus0 at cardslot0: bus 6

but PCMCIA doesn't work any better..

Is this bus information perhaps encoded in the ACPI instead but we don't
look there for it? I've put output of acpidump on www.netbsd.org:

        http://www.netbsd.org/~plunky/t60.dsdt
        http://www.netbsd.org/~plunky/t60.dump

Also, I noticed that I was wrong before - the CardBus USB2.0 card that I
have caused a panic with plain old GENERIC just now.
