I had what appeared to be a similar problem. I have a dual-head G450 PCI
card.

In my case, X was crashing and failsafe X was unable to start due to
some problem with the VESA driver, leaving the video card in a screwed-
up state so it no longer displayed anything. I was able to switch
between virtual consoles (although I couldn't see anything on the
screen, I could tell it was switching because numlock changed), and run
commands on the virtual console.

In my case, it turns out the problem was due to some InputDevice devices
in xorg.conf for a wacom tablet which is not plugged in. Removing the
unnecessary devices fixed the problem, so it was probably not related to
mga at all.
