Yeah there is a new CONFIG for a new logical DVI panel.  It should be
disabled at I guess it will have been defaulting to disabled in your
case with your own config.

If you enable it, DVI takes the approach to default to 640 x 480 even
with nothing plugged in and trashes HDMI output by setting the shared
pll.

Bug description:
  Just upgraded my packages, this pulled in linux-image-3.1.0-1402
  -linaro-lt-omap. After a reboot, there is no output on the DVI
  monitor. After restoring the boot partition from yesterday's backup
  (switching back to 3.1.0-1401-linaro-lt-omap), the DVI output works
  again.
