In bulletpoints: - Add some support for G94 and G96 reclocking. Has been tested on literally two cards, which is hardly adequate as "full coverage". On the other hand, the changes were small enough to make me confident this might work for others as well. - Fix NV50 wait for VBLANK when no monitor is plugged in. - Voltage related inprovements for GT21x. - Slightly improve Keplers
