[PATCH] xfree86: store the screen's gamma information on init.

[Peter Hutterer]

From: Bill Nottingham <notting at redhat.com>

This fixes a gamma issue on vt switch observed with KDM. VT switching away
and back would result in a black screen. Avoid this by storing the current
gamma information on init.
