So i head some problems with HDAPS on my NEW Lenovo Thinkpad T61.<br>
<pre>
Jan 13 14:53:43 xzlo hdaps: setting ec_rate=0, filter_order=1
Jan 13 14:53:43 xzlo hdaps: driver unloaded.
Jan 13 14:53:43 xzlo hdaps: LENOVO ThinkPad T61 detected, setting orientation 4
Jan 13 14:53:43 xzlo hdaps: initial mode latch is 0x05
Jan 13 14:53:43 xzlo hdaps init failed at: hdaps_check_ec failed
Jan 13 14:53:43 xzlo input: ThinkPad HDAPS joystick emulation as /devices/platform/hdaps/input/input19
Jan 13 14:53:43 xzlo input: ThinkPad HDAPS accelerometer data as /devices/platform/hdaps/input/input20

with both in kernel hdaps and the tp_smapi 0.32 - 0.34 it seams to be related to bios 2.07 acording to
<a href=http://www.nabble.com/tp_smapi-0.34-and-hdaps-td14712633.html>this on nabble</a><br>
and that patch works for me but i also changed it a bit.
