commit f77a46dc20ad21042bb30bf104ebfd186f7845c8

    Some more cleanups for vblank code on Intel.
    
    The Intel 2d driver calls modeset before reinstalling the handler on
    a vt switch.  This means that vblank status ends up getting cleared
    after it has been setup.  Restore saved values for the pipestat registers
    rather than just wiping them out.
