Pretty much. However I am making some modifications while only running RTL
simulations and not synthesizing it (or running netlist simulations). We
hope to soon release a version for Xess Virtex board running uClinux
(followed by normal Linux).

We found out that making boards causes too much problems when it comes to
money and warranty etc. So at the moment we just stick to IP.

How about Insight Electronics? Also check who is your local Xilinx
representitive/distribution.

Looks very nice. Especially because it uses Linux (said Linux fan). :-)
