[hardy], [jaunty] MSI Wind unable to turn off display because of ACPI events

[boskicinek]

Hi, when I try to turn off my display with "xset dpms force off" (or automatically, doesn't make a difference) all I got is:
1. turning off screen for a second or two,
2. Seeing my desktop back for a moment
3. blanking screen with backlight display steal on (so there's no point in DPMS at all)

In my dmesg I can see:
[ 3085.028497] atkbd.c: Unknown key pressed (translated set 2, code 0xf7 on isa0060/serio0).
