I'll try that too when I have enough time... Along with C6/C7 and
backlight control.

Yo may want to play a simple audio file, without any graphics gimmick at
the same time (video, vu-meter, anything...) which may trigger an i965

I didn't try anything linux-audio-related on mine, but remember having
heard bips and dings on Windows. I'll be extra careful not to burn
