I've seen the same thing with a ProSavage DDR-K integrated on an MSI 
motherboard.  It appears that the video card doesn't reset correctly 
when quitting X.  If X is left running, Ctrl-Alt-F1 works to switch back 
to console mode.

Other than the reset issue, the Savage video seems to work fine.

There's a UseBIOS option documented in the savage manpage, although 
"UseBIOS No" didn't help with this particular system.  Other options 
like DmaMode are probably worth trying (I would, but that system is a 
long way away).

Hmm.  A search just now turned up this:

(Link suggests disabling the Load "dri" option in the xorg.conf Module 
section may solve the problem.)

Please respond on whether that works or not.
