Hi David, I am working on the same board as you do, using the montavista linux 2.4 distribution and the eldk 3.1.1 environment. With some minor patches I've got it working with the soft ethernet core, the uartlite and the flash (although I'm still having some trouble with the flash). In the fpga design you have to change some settings to get this working too; the default will fail. I can give you the details I've found if you like.
Good luck!
