Linux users have also been experiencing those *ERROR* messages.  I'm not
sure what's going on here.  I don't think the hangs are related to the
error, since Linux people haven't been complaining about hangs.  The agp
message, however, is something I haven't seen or heard about before. 
What does dmesg| grep agp say?
