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 Marking as a duplicate of bug 466816. Cameron any additional test failures please let us know. *** This bug has been marked as a duplicate of bug 466816 *** |
