[Xorg] more patch queue

I've got a few other patches I'd like to get some opinions on before I
commit them:

1. Add gamma correction support to the radeon video overlay.  This
requires a new Xv attribute, XV_GAMMA.  This should probably be
standardized since other drivers may want to expose it (assuming they
support it) and it would be nice to use the same controls across
multiple drivers.  Since Xv attribute cannot be float values, I chose
to use integers that are 1000x the gamma value.  so a gamma of 1.2
would be 1200,  2.2 would be 2200, etc.  they can range from 0 to
5000.  Does this seem reasonable, especially since no other drivers
currently expose gamma correction of the overlay.

2. merging the savage driver from DRI cvs.  Besides experimental DRI
support, the savage driver in cvs also includes a few new features
over the old on in xorg cvs.  It'd be nice to get these in for this
release.  They include: dpms support for LCDs, interpolation on Xv
scaling, and many more fixes and clean ups.  I also have dualhead
support (duoview) working for mobile savages, but it still has a few
bugs at the moment, so that'll have to wait.
