That's for 3d though. It should support higher resolutions for 2d. And
IIRC the main difference between the Riva 128 and Riva 128ZX was that
the latter had a 8MB frame buffer, so some deviation from the "ideal"
frame buffer size :-). Maybe the log offers some insight why it is stuck
at this resolution, I have no idea about this driver though.
