Ah, that's the thing.... I never did anything special to make it work! It just 
worked, which is why I assumed it was controlled in hardware. The example I 
gave above was to back up that assumption. ie: would you trust windows to look 
after cooling your cpu?!!! ha ha! I know for certain than lm_sensors is nothing 
to do with it.

If your fan never slows, you may have a hardware problem, thinking about it. If 
the temperature sensor has failed it'll run the fan continuously as a failsafe. 
I'm surprised you're not getting any POST errors though.

It's the DVD movie playback I'm struggling with. Reading DVD data cds works a 
charm. I've got the hacked neomagic driver for XFree86 4.2.0 with support for 
Xv but it's still jerky. Any ideas? I've run out of things to try.
