beep: working
brightness: reading yes, nothing happens on writing, i dont
know if it happend to work before
fan: hmm, need to reboot to reload module with parameters,
but reads a level 3 when fan on
hotkey: seems to work, all FN keys are working
led: working
light: working
thermal: working
video: working
volume: reading yes, writing no
