You've been lied to, the Saphire uses a 128-bit memory bus, from their second 9500 non-pro PCB. It sux all the way around, performing significantly worse than a 9600 Pro.
Perhaps they meant to say it has a 256-bit processor? At any rate, even if you hacked it to enable 8 pipes, and even if that hack worked, you'd still have less than half the memory bandwidth of the 9800 Pro.
