The two busses are multiplexed by a single controller. I wouldn't expect
much of a difference in splitting drives across the busses. You should
also be aware that the controller only allows 4 concurrent transactions
and that you will most certainly run into the "can't sleep waiting for
openings" problem in NetBSD's SCSI system if you play with CCD because
of this small number of controller resources.
