Hmm, some of the Intel chipset code has resume callbacks already. These _will_ get called even if AGP isn't in use. I'm wondering if they're doing something they shouldn't. It might even be possible that those callbacks should just do nothing if agp isn't in use. Need to think some more on this one.
