I'll try to revert 9d0498a2bf7455159b317f19531a3e5db2ecc9c4 and see if
that helps.

Thanks for the confirmation Pekka. I've managed to change the resolution
but gdm always starts with 1024x768 and upon login it gets 1280x1024,
and sometimes the mouse pointer go out of bounds to the right edge of
the screen but when I maximize windows it sticks to 1280x1024. When I
start gnome-display-properties that invisible right portion of the
screen dissapears.
