Description of problem:
ThinkPad T41 running F13 Alpha with updates

Starting with the 2.6.33.1-26 kernel the system immediately panics on boot in the ACPI code.
the system boots normally with older kernels or by booting with acpi=off

Version-Release number of selected component (if applicable):
>= kernel-2.6.33.1-26 panics on boot (tested up to kernel-2.6.33.2-38.fc13)
<= kernel-2.6.33.1-24 works fine

How reproducible:
Each boot

Steps to Reproduce:
1. ThinkPad T41
2. Install kernel-2.6.33.1-26 or newer
3.
  
Actual results:
Panic on boot

Expected results:
Normal boot

Additional info:
Panic is not logged
