I've noticed that in the latest macbook models (since Santa Rosa model) the
applesmc driver can't manage the motion sensor correctly. It detects it
normally at boot time, but if you try to access to
the "/sys/devices/platform/applesmc.768/position" file you get an I/O error.
This is not obviously a critical error, but it makes impossible to play games
like neverball or tux race by moving the laptop (that's very cool), or to use
programs like mactap.
Is there any solution to this trouble?
Thank you very much, and excuse me for my horrible english
