Ah good. Does the driver actuall re-POST the chip completely or is it not necessary ? I suppose the fact that it's an integrated chipset makes things easier... With ATI radeons, one of the major pains is to re-initialize the memory controller and internal clock net. I've reverse enineered it from the MacOS driver for some chips used on apple laptops but it's still far from a generic solution. Ben.
