Could you provide "dmesg" output? Is agp(4) enabled in your kernel
configuration?

Can you please provide more information? What does "/var/log/XFree86.0.log"
say? Could you "ktruss" the X11 server, please?

This is probably related to the import of XFree86 4.5.0. The ATI driver
still works for various graphic cards (e.g. Radeon 8500 or 9800 Pro).
My guess is that it is a problem specific to the chipset of your notebook.

	Kind regards
