Up until now the problem was only present on the new models, T400, T500 and 
X200 (according to thinkwiki)
Did you update your bios recently Kai? Maybe Lenovo introduced the faulty 
setting into the BIOS of the T61 as well....

On the other hand there is a T400 bios update which fixes the tp_smapi issue, 
the current one is v2.07 (even though only 2.03 is announced on the driver 
overview page)
