Actually we really should make load_cursor_argb return something other
than void.  Some particularly incapable server GPUs have format
restrictions on their hardware cursors that mean _some_ ARGB cursors
could be made to work but not all; and right now, the fallback code in
-modesetting doesn't get this case right, and you end up with no cursor
at all.
