Well, at least it avoided one kernel warning. Or rather, I haven't seen 
it since. But otherwise, the cursor works fine. I don't have any 
problems with the cursor whatsoever, it always appears.

It's hard to say whether it is needed, unfortunately. The kernel warning 
is not so easy to provoke, and there is no clear way to reproduce it. 
All I can say is that I haven't seen it since, and the patch has surely 
not made anything worse, so I would say go for it and include it.
