I've always been partial to OC-3's here. Heheh...just kidding.

I haven't set up multiple NIC's in one box, but at one time thought
about it. From what I read, any NIC beyond the first might require a
kernel option to reserve the io address that the 2nd NIC will take, and
then setting it up after bootup. The initial detect stuff is apparently
only designed for a single NIC (all of this was before devfs, which I'd
avoid). I'm tempted to throw a cheap ne2000 compatible in on one of my
machines, because I want to run some network [poor] condition kernel
modules on it (to look at how client/server software does in different
degraded conditions).
