Seeing the same thing with a radeon 9200 AGP and radeon 9200SE PCI. 
Works great with 6.8.2 on SuSE and Gentoo.  Doesn't work with 6.9/7.0 on 
any distribution.  Keyboard dead, sometimes mouse movements can occur, 
but system is unresponsive with xorg at 100% cpu.  Can SSH into system 
from another machine.  Second monitor has random colors cycling on it, 
primary monitor gets part way thru gnome start-up after loggin in via gdm.
