It just needs to be someplace where appropriate interlocking with other 
device access can be done; given a kernel driver for the card aiding 
rendering, it seems useful to place the cursor register manipulation 
there as well.  I suppose it could be arranged so that user-mode could 
know when it was safe to update the cursor registers somehow, that would 
work just as well.
