More than six, yes.  I've been using a Compaq Proliant 3000 (PIII-500,
256MB) with six Intel EtherExpress PRO 10/100B's (82558) and one Dual
EtherExpress PRO 10/100B (dual 82558 + PCI bridge) for a total of 8
interfaces.  FreeBSD 3.1-RELEASE didn't want to see all of the PCI
busses in this particular server, but 3.2 saw everything just fine,
and works without a hitch.  I could easily put 10 interfaces in this
thing since it has a couple of free PCI slots, and I wouldn't forsee a
problem doing so.

The performance is quite good, by the way.  I've managed to saturate 4
of the interfaces at 100Mbit FD and the server didn't break a sweat.  
This was with 36 ipfw rules, with most of the traffic passing through
14 rules on its way in and out (exactly 28 rules for a packet to pass
through the box from one of my private networks to another).  
Granted, this was a bunch of SMB traffic passing between multiple NT
(blech) boxes, so the packets on average were fairly large.

Maybe in a few months, time allowing, I'll set up some workstations on
each of the networks to pump as much data as they can through all 8
interfaces, packets both big and small, and see how it performs.
