[coreboot] please suggest

[marty]

I wish to use coreboot for a firewall design.
I need to have iptables/modules/and drop policy all loaded before 
networking is enabled. I can do the rest from disk.
I will need 2 slots for Ethernet cards.
I need 2G RAM capability.
I prefer a 3.x version Linux kernel.

From what I see, most BIOS chips seem a bit small for this.
I don't need high-end hardware; domestic stuff is preferred.
Definately no Realtec 8169 however... Gaa...

Can someone please suggest a board(s) that might suit my needs,
and is well supported by coreboot?

Thank you,

Marty B.
