The Geode X driver uses both of the LX's palettes, one for gamma
correction and one for colormaps.

The kernel driver currently only backs up the one used for colormaps
during suspend/resume. If you mess with gamma settings and do a
suspend/resume, colors go funny.

Fix this by backing up the video proc palette during suspend/resume,
alongside the display controller one which is already handled.
