[Thinkpad] keyboard problem / keys stay locked

["Nicholas A. Preyss" <nalp@gmx.net>]

Hi,

another of the small problems i face during running Linux on my Thinkpad R32 
seems related to the keyboard driver. The keys Control (both), Alt, AltGr,
Shift (both) seem sometimes to stay pressed after using it. After
pressing the key another time, this behaviour ends and all works normal
again. This happens very unregulary. My thinkpad is featured with a
de_CH keyboard, but i had contact with another R32 user with de_DE
layout who faced the same problem..
