modesetting xserver change breaks drivers...

[David Miller]

The following commit requires all drivers providing crtc funcs to be
rebuilt because the new function pointer will be, at best, garbage,
since the crtc funcs structure layout has changed.

Don't we need to do a version bump or something like that when this
happens?

    xf86Crtc: add higher level modesetting entry point.
    
    For kernel modesetting work we need a bigger stick to beat the modesetting path
