I debugged a case exactly like this (with the TRACE_RESUME() thing) back last November on my laptop. The problem is that radeonfb actually *tries* to re-initialize the graphics chips, but because it doesn't know all the details, it does it wrong, and hangs the whole chip. I forget exactly where it happened, and it might well be different for you. But this is exactly what TRACE_RESUME can be used to pinpoint if you want to try to debug it.
