Ah, O.K. - so they dont necessarily have better I/O bandwidth in 64 bit
mode than they do in 32 bit mode then ? I am still quite keen to move to
a 64 bit architecture though. I am having problems to get the system to boot
SMP, and all the people who ahve told me that they can make it run on the
same motherboard are using amd64.
