Patch 7513: Removes the unused Proc.movetime variable and a comment
describing the algorithm which once used it.  Trivial, tested, and
working.

Patch 7514: Makes the vgaradeon driver compile on amd64.  GRUB sets up
my framebuffer, so I have not yet tested it.

Patches 7515, 7517, 7518: Adds CPU frequency scaling support for AMD
family 10h and later, and sets the lowest-power state during boot.
Tested and working on one of my family 10h systems.  I don't consider
it finished, but it is worth applying upstream.  Note that the
'powersave' command prints out PstateMaxVal; this should probably be
removed someday, but not until it has been tested more broadly.

Patch 7516 (note out of sequence): Fixes a comment typo in bootrc.
Trivial, tested, and working.
