Hm. I gues this would be the best place though.

Not for my Omnibook 800

I am no apm expert at all. From looking at the rev 1.2 bios interface
spec, it looks like the Set Power State command (0x07) with device id
0x01xx and Power state 0x03 could do the trick. Even if not from
wscons, but then from apm. Perhaps it would be an idea, when wscons
just had two hooks, that call a external tool after some time without
activity (blank screen) and to redisplay. This would allow for
different "screen savers" like e.g screen blanking or calling lock(1).
