If these NICs are 3c509s on the ISA bus, they aren't PnP. It's hard to
understand how *any* two work together, since they should have fixed IRQ
assignments that will often conflict. Some pairs might work, but if all
possible pairs work, then so should all possible triples and quads (except
that I didn't realize that you could find P75s with 4 isa slots).

When you say adding the other two "has no effect" ... what effects have you
looked for? Most interface-related commands report only *configured*
interfaces. The command "ifconfig -a" is the important exception (it's the
main reason I'm unhappy when ifconfig isn't part of distros). Do you see any
reports of the NICs during boot/init? If you try to hand configure eth2 or
eth3 from the command line, what happens?

While there is something wrong with your setup, what you've told us isn't
quite enough to identify what that something is.
