My problem isn't that X doesn't work, it's that any kind of access to the
framebuffer memory "eventually" (after some period of activity) hangs the
system. I don't know what is actually causing this, as I don't know what memory
block is implicitly shared by the video memory and real memory, which makes this
a very difficult problem to solve. And, yes, I do have an ATI card (9600).
