This thread came up on linux-poweredge a month ago. Here was my
response then:

There you'll also find a script I wrote, name_eths, which does its
best to assign ethX names in ascending order, first choosing the LAN
ports on the motherboard, then ascending by slot number, and if you've
got a multiport card in a slot, then by ascending MAC addresses on
that card. It rewrites the HWADDR lines in the
/etc/sysconfig/network-scripts/ifcfg-ethX files to then match this
ordering.

http://linux.dell.com/files/name_eths/name_eths-0 (See http://ths-0.ora-code.com).1.tar.gz.sign
As always, this isn't Dell-supported, or by anyone else for that matter.
It appears to do what you're looking for.
Thanks,
Matt
