 It looks like agp_generic_attach is trying to create two device nodes
 both named "/dev/agpgart" with no unit numbers.  That's a no-no, which
 is why you're getting EEXIST (errno 17).  As a workaround, try
 disabling merely one of your two AGP devices.  That will probably fix
 the panic.
 
 The next question is: why do you have two AGP devices?
