Break the mouse cursor, fix resolution changing

I suspect that the resolution changes are only a part of this problem. Now that I've got some hardware to test on I noticed that moving the mouse changes the behaviour of the broken screen, so I suspected that the hardware cursor might be involved.

Investigating this, I came up with the attached patch which simply causes all calls to set the cursor to set a null cursor. This fixes resolution changing for me - I can cycle through the xrandr mode list to my heart's content.

Of course, this patch also ensures that you can never see a mouse cursor, so it's hardly a fix.
