Cursors should just work (tm) with full pipe rotation. You get into a
bit more trouble if you rotate just the cursor plane since then you get
to fix up the dst coordinates if your visible cursor is smaller than the
fixed cursor size. Or did you mean something else?

BTW if you want to try it, I pushed the lot to:
git://gitorious.org/vsyrjala/linux.git rotate_latest_2
