Hello,
I would just like to politely draw attention to this again. I would
assume from the silence that the people who might review it don't think
it is a completely wrong thing (that would not take long to say) but
don't have the spare cycles to take a closer look. Any idea when
someone might have twenty minutes to review it?
Regards,
Michael

Currently if modesetting ever fails to set a hardware cursor it will switch
to using a software cursor and never go back. Change this to try a hardware
cursor first every time a new one is set. This is needed because hardware
may be able to handle some cursors in harware and others not, or virtual
hardware may be able to handle hardware cursors at some times and not others.
