nice :) I have the same chipset, but the 3D acceleration freeze my
machine, currently I'm using the kernel 2.6.25-rc8 (I'm too lazy to
compile the lastest :P) because with this one I can have EnableAGPDMA
seted to true.

what mesa libs are you using?, do you use f-spot?, that freeze the
machine thanks to nice a bug on unichrome_dri module.

I don't know if that's is top power of the card (probably not), but at
least is better than software rendering :)

somebody knows about that IRQs related message?
