    Untangle XF86DRI from the driver-specific DRI define
    
    XF86DRI is defined by xorg-server.h, so --disable-dri in the sis driver
    itself does exactly nothing other than not fill in the CFLAGS and thus stop
    the driver from compiling.

    Use miPointerSetPosition, not miPointerAbsoluteCursor
    
    miPointerAbsoluteCursor was removed in '09.
    
    Technically this shouldn't just work on the VCP since any master pointer may
    end up in the dead area. However, I suspect the Venn diagramm of MPX users
    and sis merged framebuffer users shows little overlap.
    
    miPointerSetPosition's prototype changed a few times, these are a bunch of
    untested ifdefs that should be correct according to the git history.
