If X is indeed running on the affected monitor, and you can get remote authority to write to the X server driving your VGA port, you might be able to control the output using "xrandr". It might also be possible to specify an xrandr command line for the display manager's benefit.
X.org configuration has gone largely automatic, but it should still be possible to constrain the monitor settings without going full-tilt into CRTC timings...
Certainly the /var/log/Xorg.0.log or whatever it is called these days might be useful to look at to see why it might be giving bad timing. -- Len Sorensen
