The current fglrx driver supports that. The one that comes with breezy
may be too old though.

Note that the snapshots' install script doesn't support the Xorg 7.0
directory layout yet. :-( I'll work on that, probably on the weekend. By
the time Dapper is released, it will hopefully have the recent updates
in the Radeon driver. Otherwise lots of Radeon owners will see this
nasty regression when they upgrade. Hail the modular Xorg that makes
individual driver updates easy. ;-)
All that said, IME the Xorg vesa driver is pretty usable in terms of 2D
performance even though it has no hardware acceleration at all.
