Do you have a second computer you could ssh in to the first to restart
X from?

I just hit this problem this morning on another computer, this time
with an RV380.  Pretty much exactly what you describe - black screen,
no flicker, nothing fixed it.  I was not able to switch to a text VT,
but that hasn't worked on this box in a long time.

I sshed in from a laptop and restarted X and that fixed it.  This
seems new with xserver-xorg-video-radeon 1:6.12.6-1.  Haven't had a
chance to try the fixes.
