    Honor Option "NoDDC" correctly
    
    Move xf86CollectOptions before the DDC code so it can actually hear us
    when we ask to disable DDC.

    Use VBEFreeVBEInfo not free
    
    A VbeInfoBlock has substructure, just freeing the object will leak.
    Unfortunately VBEFreeVBEInfo does not check for NULL first so we have
    to.

    Fall back to VGA if the palette API isn't supported
    
    I ported vesa to use the VBE service back in:

    	Use VBE palette load, not VGA banging.
    
    I'm reasonably sure that worked on all the hardware I had handy at the
    time. But it doesn't work in seabios, which means 8bpp is broken under
    qemu.
    
    We query this API early in initialization, and if it fails ->savedPal
    will be NULL, so use that as the hint to fall back to VGA banging.

    Don't build old probe method on sufficiently new servers
    
    If we have pciaccess and not ISA support VESAProbe is effectively return
    FALSE, and the server will issue a potentially confusing fallback
    message if VESAPciProbe failed and ->Probe is non-NULL.
