Yes, the fc7 kernel is a bit of a trainwreck. 2.6.21 wasn't particularly
good for suspend/resume but 2.6.22 is much better. Could you try a
kernel from rawhide and see if you still need to remove those modules?

We did, but then we had to remove most of them. Lots of the quirks were
incorrect, or just obsolete. Some quirks change over time as there are
major kernel p/m updates or when the XOrg drivers change. For instance,
using the i810 and intel drivers you have to use different quirks for
the same hardware.

We've also been committing quirks very fast, and the new database has
grown very quickly. Just today I've committed about 7 quirks.

See above. Cheers for the patch, appreciated.
