   For actual data transfers, you are absolutely correct.  But the bus 
transactions required to set up those transactions are still highly 
CPU-centric.  Admittedly this is nowhere near as bad as it could be, 
and I don't mean to suggest that it's a major issue.

   Nope, but I'll be working on it again in another week or so.  I had 
been hoping for a bit of a reprieve from the QYX project a month or so 
ago, but it's finally coming next week...it's finally going into 
classrooms.  I'll have a bit of a break before the bug reports and 
feedback start rolling in.
