Bug Description
Binary package hint: linux-source-2.6.24 (and 2.6.26 for post-Hardy)
Thinkpad_acpi 0.19-20080321 is available for 2.6.23 through 2.6.26, so the backporting effort should be essentially done for the Ubuntu team. The current version packaged with Hardy (2.6.24-based) is 0.17. The litany of features and fixes can be found in the release notes for the intervening releases, including a number of issues for newer Thinkpad laptops and tablets including:
* Fix numerous problems and bugs in the NVRAM polling support
* Fix severe problems in the 16-level brightness support
* Add functionality to disable brightness support if there is ACPI standard support for it in the BIOS
* Update backlight support according to comments from the linux-acpi ML. Now it can be selected at runtime
* Fix brightness error path
* Notify userspace of hot-unplug events that wake up the box
* Lenovo keymap changes to avoid duplicate brightness up/down events.
* Fix NVRAM polling support to deal properly with hotkey_mask
* Reason for wake-up reporting added (mainly for eject/undock)
* New *61 HKEY events
* poll()/select() support in a few key attributes
* Fixes to the NVRAM polling interface
* always track input device open/close
* synchronize input device switches
* switch Lenovo BIOS to ACPI backlight mode
* make the video output feature optional
* issue input events for tablet swivel events
* improve thinkpad-acpi input device documentation
* minor hotkey_radio_sw fixes
* tablet-mode reporting
* enhance box identification output
* rate-limit CMOS/EC unsynced error messages
* fix brightness dimming control bug
* add support to leds with readable status
* prepare light and LED for sysfs support

* Fix led trigger/list_lock locking bugs

Here's the git tree for the driver http:// repo.or. cz/w/linux- 2.6/linux- acpi-2. 6/ibm-acpi- 2.6.git . It would be interesting to find out whether this newer version would autoload the thinkpad_acpi module on the lenovo T60 I am using...
