Yuck indeed.  Because the 3c509 has a very small buffer it interupts 
the system early, so the processor can handle the processing that 
should have been done on the card.  The 3c509 is OK, but not great, 
as a workstation NIC.  It really falls down as a server NIC.  It 
makes heavy demands on the system, and it tends to cause dropped 
and mangled packets.  I am truly surprised you were getting decent 
performance with 4 3c509's in a system.

I'd suggest switching to other NICs.  Almost any other NICs.

If you are in a coax environment, or if you aren't going to move 
towards 100baseT any time soon, I'd look at the NE2000 clones.  
They're cheap, they're reliable... they're not a bad choice.

If you are in a 10baseT environment, especially if you think you're 
moving towards 100baseT, I'd look at switching to faster cards.  
There are a number of decent inexpensive cards based on the DEC 
chip set.  I've had good results with DLink, LinkSYS, and NetGear 
(ONLY with FreeBSD drivers though, I do NOT recommend NetGear 
for DOS or Windows).  

Intel makes a number of nice cards, some for servers, some for 
desktops.  All of them are good enough to use in servers, but the 
ones Intel calls server cards have more intelligence on them, 
reducing the load on your machine.  They make a server NIC with 
multiple (well, two) ports on a single PCI card.  I'm not sure if 
FreeBSD has support for the Intel server NICs, but if the support is 
there, those are very nice cards.  Intel does make 10/100 cards for 
ISA slots, which could also be a consideration for you.
