    Make all G4X chips use the new framecount register.
    The G45 docs indicate that all G4X chips use the new framecount register.
    Intel agrees with my reading of the docs, make it so for all G4X chips.
    The new register also has a 32 bit width as opposed to 24 bits.  Fix
    things up so that the counters roll over properly.
