CPU gets hot, if left in this state. With acpi=off system hangs early on boot as well, at 'probing PCI ...' Steps to reproduce:
There have been zero ACPI changes between 2.6.16.1 and 2.6.17-rc1 bumping this over to the PCI sub-system.
I experience the same on 2.6.17 final on a HP Compaq dc7600. Linux 2.6.16.1 works fine. When booting with acpi=off, console shows the following before freezing: unknown bus type 255. (repeatedly) ..TIMER: vector=0x31 acpi1=-1 pin1=-1 acpi2=-1 pin2=-1 ...trying to setup timer (IRQ0) through the 8259A... failed ...trying to setup timer as Virtual Wire IRQ... works.

Based on email comments, this is fixed in 2.6.17-git10, so am closing it.
On my Toshiba Portegee M400 the problem still exists.
