Setting to 5.2 and requesting an exception. This is a regression that is
affecting a large scale deployment for LVM.
Comment 4 RHEL Product and Program Management 2008-03-19 09:36:22 EDT
Since Keyword Regression exists, this is a blocker,
not an exception.  Cleared exception flag.
Set blocker flag."

The version of the ibm-acpi driver in 5 appears to be sufficiently old that it
doesn't know how to drive the hardware on the T61.

This is the feedback I received from Richard on this issue: 

> The T61 changed the way the brightness was controlled, and so RHEL has
> get zero chance of this working without updating the version of ibm_acpi
> to thinkpad_acpi -- there are quite a few big changes in the driver too.

thinkpad_acpi is in the 5.3 kernel
