With the NPE-G1, if you have an I/O controller, the port(s) on that board
do not count towards b/w points on the two PA busses.  With

http://www.cisco.com/warp/public/cc/pd/ifaa/prossor/prodlit/npeg1_ds.htm

"Frees the current I/O controller ports from bandwidth limitations, 
allowing two PCI buses to be dedicated to the port adapter slots"

Any other NPE/NSE, and the I/O controller does consume b/w points.
