Thanks for doing the bsearch - it helps.

There were no driver changes between 2.6.11-rc4 and 2.6.11-rc5.

The only PCI change I see is

--- drivers/pci/pci.c 22 Jan 2005 03:20:37 -0000 1.71
+++ drivers/pci/pci.c 24 Feb 2005 18:02:37 -0000 1.72

return -EIO;

pci_read_config_word(dev,pm + PCI_PM_PMC,&pmc);
- if ((pmc & PCI_PM_CAP_VER_MASK) != 2) {
+ if ((pmc & PCI_PM_CAP_VER_MASK) > 2) {
printk(KERN_DEBUG
"PCI: %s has unsupported PM cap regs version (%u)\n",
dev->slot_name, pmc & PCI_PM_CAP_VER_MASK);
and you're not getting that message (are you?)

Nothing much in arch/i386..

There were some ACPI changes, which is always a worry ;) Does that machine
run OK without ACPI support? If so, could you determine whether disabling
ACPI fixes things up?
