Buy the D-link quad NIC. It's DEAD cheap and is PCI (no PCI-express). Don't start about performance on this card, but why would you bother about performance in a Dynamips lab :-)

For frame-relay you don't need to do anything. Grab a topology from a vendor, all supply a .net file that you can immediately use within Dynagen/Dynamips. Within that .net file you have all the Frame-Relay mappings that you will need (Dynamips has a built-in frame-relay emulator).
