I'm pretty sure the 7200's bridged 3 PCI buses are the fast PCI bus, clocking 
at 533 MBps, but just because they come out with an interface for a box
doesn't meant that that box can realistically support it. It's not unheard of
for vendors to come out with a box that you can over subscribe. 7200's max
throughput is about 3-4 DS3s..

Also, 7200s don't have VIP2s. 7200 is basically a VIP2 in a chassis.
