Description of problem:
kernel-2.6.12-1.1447_FC4 fails to load the ibm_acpi module on boot.  This
prevents ACPI functions such as sleep, hotkeys, etc. from working.

Version-Release number of selected component (if applicable):
kernel-2.6.12-1.1447_FC4

How reproducible:
Always

Steps to Reproduce:
1. Boot kernel-2.6.12-1.1447_FC4 on a Thinkpad
2. lsmod | grep ibm_acpi
3.
  
Actual results:
ibm_acpi is not loaded

Expected results:
ibm_acpi should be loaded

Additional info:
This is a regression from kernel-2.6.12-1.1398_FC4, which works perfectly.

Attempting to load the module by hand produces:
# modprobe -v ibm_acpi
insmod /lib/modules/2.6.12-1.1447_FC4/kernel/drivers/acpi/ibm_acpi.ko
ibm_acpi: Using generic hotkey driver
FATAL: Error inserting ibm_acpi
(/lib/modules/2.6.12-1.1447_FC4/kernel/drivers/acpi/ibm_acpi.ko): No such device
