Hi,
I get this in dmesg with 2.6.17 :
ACPI: bus type pci registered
PCI: Using MMCONFIG
Setting up standard PCI resources
ACPI: Subsystem revision 20060127
ACPI: Interpreter enabled
ACPI: Using IOAPIC for interrupt routing
ACPI: PCI Root Bridge [PCI0] (0000:00)
PCI: Probing PCI hardware (bus 00)
ACPI: Assume root bridge [\_SB_.PCI0] bus is 0
PCI quirk: region 1000-107f claimed by ICH6 ACPI/GPIO/TCO
PCI quirk: region 1080-10bf claimed by ICH6 GPIO
PCI: Ignoring BAR0-3 of IDE controller 0000:00:1f.2
Boot video device is 0000:01:00.0
PCI: Transparent bridge - 0000:00:1e.0
PCI: Bus #04 (-#07) is hidden behind transparent bridge #03 (-#04)
(try 'pci=assign-busses')
Please report the result to linux-kernel to fix this permanently

Seems to work fine either way.
