If you want to simply add a high-speed connection, you may be better off with an FTDI chip attached to the USB connection. I don't know how fast the FT232RL is, but the FT232H has a parallel interface that is certainly fast enough to get all the USB2 bandwidth.

btw, I found open-rd.org. as far as i see it is a sheeva-plug, and there are both software, hardware schematics etc... i think the seeva-plug derivatives (e.g seagate dockstar) are a subset of that design I saw websites with instructions on how to add anothe GBE or how to add an SD to the
