Here is some fresh information for Linux on the T61/R61 (and likely X61..
untested). Someone with a T61 or R61 please test and update thinkwiki.
First, you must be aware that your model works differently than older
ThinkPads. The EC has different behaviour for various things.

Here is a bunch of thinkpad-acpi changes that fixes some bugs and add key
thinkpad models support that should, if at all possible, be merged for
2.6.24.
They are really important for ThinkPad X60, T61 and R61 users, and the
first patch unbreaks the ThinkPad ACPI hotkey map in all IBM ThinkPa

Lenovo ThinkPads often have 16 brightness levels in EC, and not just eight
levels like older ThinkPads. They also have standard ACPI backlight
brightness control.
We detect the number of brightness levels by the presence of a BCLL package
with 16 entries. If BCLL is not there, we assume eight le
The lm-sensors 3.0.0/libsensors4 compatibility changes are reason enough to
bump up the version string. Do it.

Revert commit fba956c46a72f9e7503fd464ffee43c632307e31, "Map volume and
brightness events on thinkpads".
That commit made some modifications to the default keymaps that cause bad
behaviour on all IBM ThinkPads if HAL doesn't know to change them into
passive (on-screen-display only) events.

Map an mutex_lock_interruptible() error return into ERESTARTSYS, as the
only possible error from mutex_lock_interruptible is EINTR, and that will
only happen if signal_pending() causes the mutex lock attempt to abort.
This still allows signals to be delivered ASAP, which is much nicer than

Newer Lenovo BIOSes support the standard ACPI backlight brightness
interface (_BCM, _BQC, _BCL). It should be used instead of the native
thinkpad backlight brightness control interface when possible.
This patch disables the native brightness support in the driver by default
when we detect that th
The code calling brightness_set() can't handle EINTR/ERESTARTSYS well, nor
is it checking brightness_set() return status properly.
Fix it.

Err, brightness_enable. The patch is correct, though. I will send an
updated one which fixes the description, just i
