Yes, that's why I stated that the patch is for ICH3-M, and possibly other ICH-M chipsets in the original mail. I don't know a thing on how C3 is done on other processors and chipsets. I'm willing to learn and implement that (hence my questions about a more general solution for chipset-specific stuff) provided there are potential users. So far, nobody except you and Len has answered. I might try rephrasing the original mail and post it to lkml now that I'm fairly certain the patch doesn't cause any corruption on my system though.
