I have put in a little work looking at hardware cursor support and

The radeon_hd driver seems to work perfectly well on my Radeon 6870,
so adding hardware cursor support using the original accelerant method (set_cursor_shape) would be helpful, but we also need to expand with a 
new hook to support bitmap cursors.


I'm neck-deep in Gallium at the moment.
If someone wants to give RadeonHD a whirl.. feel free.

Otherwise it may be a while until I have the time.

How Linux does it:

It looks like you don't even have to go through AtomBIOS to wrangle the cursor.
