In a PCI-X 133mhz, 64bit slot, it looks like it could get pretty close 
to saturating a half-duplex connection. The question is, how much CPU 
would you need to bridge/route one (or a pair) of these guys?

Can anyone think of a good reason to use one of these things instead of 
a few 1xGE connections (like a quad port GE card?)
