How does translating this datasheet actually work? I have a ICH8 myself and would like to know if I can save some power with your trick, but I'd like to understand how you managed to translate "PM-D31:F0" and "Offset A0h" into 00:1f.0 a0.b and why you're setting it to 7... Does a0.b mean row "a0" and column "b" (=11th) ? But this one isn't 7 in your example, it seems to be "0a"... It would be nice if someone could explain this, maybe even with some background infos...we must have some gurus on this mailing list ;)
