No, this patch is Radeon specific; it just uses the ARGB hardware for all 
cursors instead of switching back and forth between 2-bit and 32-bit 
cursors.

The core->ARGB conversion is done within the Radeon cursor code in a tiny 
loop.  A future extension could push this conversion into the cursor code 
permitting any ARGB-capable hardware of easily doing the same thing.
