Rolling back files below while keeping the rest of the tree current as
of 21:40 EST eliminated crash for me:

acpi_pci_link.c: 1.33 2004/09/25 06:15:56
acpi_pcib.c: 1.51 2004/11/11 22:33:08
acpi_pcib_acpi.c: 1.45 2004/11/09 07:02:33 
acpi_pcib_pci.c: 1.10 2004/08/11 14:52:50
acpi_pcibvar.h: 1.3 2004/08/11 14:52:50

I can try patches or provide any additional details. Unfortunately,
panic kicks in way before my remote console (PCMCIA Firewire), so
backtraces would have to be hand-trascribed. Current one looks
sufficiently like one above that I do not think it will add any value.
