hdapsd 1:20090401-2 (powerpc binary) in ubuntu natty

 This is a disk protection user-space daemon. It monitors the acceleration
 values through the HDAPS or AMS interface and automatically initiates disk
 head parking if a fall or sliding of the laptop is detected.
 .
 It is recommended that you use this daemon with the hdaps module provided
 by tp-smapi rather the one in the kernel, as this will save you a bit
 power and will work on a wider range of ThinkPads.
