Well thanks for your help, but actually the reason why I reported this bug is because most newer Thinkpad models are not supported by hdaps and the hdaps_ec module is not available...
% sudo modprobe hdaps
FATAL: Error inserting hdaps (/lib/modules/2.6.27-9-generic/kernel/drivers/hwmon/hdaps.ko): No such device
% dmesg | tail
[ 5029.144387] hdaps: supported laptop not found!
[ 5029.144400] hdaps: driver init failed (ret=-19)!
% sudo modprobe hdaps_ec
FATAL: Module hdaps_ec not found.
