tg3 cards

I have an IBM x336 server with two onboard Broadcom cards which use the
tg3 driver.  I also have in the same server, a 2 port Broadcom card,
which also uses the tg3 driver.  I'm running RHEL ES 3.0 update 3, which
makes the onboard nics eth2 and eth3 and the pci card nics eth0 and
eth1.  I would like to force the onboard nics to be eth0 and eth1, while
the pci nics are eth2 and eth3.  Any ideas?


thanks,
Daniel
