I've a ATI Radeon Mobility M7 with similar symptoms, however, there are
slight differences and tricks to get the screen back.

The difference I have is that the screen lights up again from graphics
mode blanking, but is really messed up (random twitching, looks very 
unhealthy).

The fix is to switch to a text-only screen, switch off the LCD lighting if
it's on, then on again on the text screen, and the image will come back
nicely -most- times (if it doesn't, a second try of lights off/lights on
will usually work). Going back to the graphics screen (i.e. X) will then
also work fine.

Also: at work I have a Linux box with an ATI Mach64 graphics card and 
an LCD monitor that has the same problem (with the screen staying
blank, not going into twitch mode), and the same workaround works too.

kind regards,
