915resolution is a noop now.

This looks very much like a server bug I fixed a few weeks back.  Please
update to server from git and try again.

If that doesn't help, please open a bug with the full Xorg.0.log as an
attachment. Also, try using xrandr --verbose to get hex IDs for all your
video modes and try the relevant ones (xrandr --output VGA --mode
0xwhatever) to see which ones work correctly.
