...and, fwiw, they also have a mini-pci version that is geared for 
their net4501, etc. single-board computers.  Since these things have 
AMD SC520 or NS Geode CPUs on them, the offload card is faster than the 
CPU :-)

(Though, you have to beware -- if you're using all 3 10/100 ports on 
the net4501, there is very little PCI bus bandwidth left over for the 
Hifn, so design your system accordingly.)
