Nod.  It's my gut feeling that a small capacity card would find 
itself in a wait state before flooding the CPU with interrupts.  Then 
again, I have very little experience in the network card area.  

I've got a fairly old card on this machine, DEC Etherworks LC/TP 
(DE-101?) and it's in a 400mhz MMX P2.  Dunno if this card will
cause problems.  It doesn't with 5 users <grin>
