I have it in my Notebook, too. Its a 1.2 GHZ P3. For DVDs it uses usually
20-30% CPU for DVD playback with sdl or xv. Usually I use xv.
For DivX its usually around 5%, mostly less ( often <1% ) for high bitrate/
high motion its sometimes around 15%, rarely more.

Gl is slow for me, too. It uses around 50%-80%

Sorry I have no idea. Well my System is a gentoo and thus heavily optimized
for the used hardware but that shoudn't get you into that much problems if
you haven't.
And I'm still using XFree86 4.2, but that shouldn't be that much of a
problem neither. Is your Chip an (RM M6) LY chip, too?
