Odd, it does look like agp0 did attach then.

That's just telling you that you have an AGP video card, it doesn't mean 
anything as far as if the GART is working or not.

This message means that the GART is not working somehow, or that the radeon(4) 
driver can't work with it.  You can try asking Eric Anholt 
(anholt at FreeBSD.org) if he has any ideas.
