But I think it may be of interest here too.

I hereby present my open source FPGA litecoin miner https://github.com/kramble/FPGA-Litecoin-Miner
Now don't get too excited. I only wrote it because I couldn't find one on the net, and its pretty crude as I'm an amateur at FPGAs. Its a direct port of scrypt.c using the on-chip FPGA RAM. Performance is quite pathetic at around 1kHash/sec per core (and I estimate 4 cores will fit on a LX150).
The initial version is compiled for a DE0-Nano (since that's what I have), but I have also done a version for the DE2-115 (simulated only).
I will need some help with a Xilinx LX150 port as I don't have a board to test on, and I don't have an LX150 Xilinx ISE licence (though I could obtain a 30 day trial). Though to be honest, its not really worth the effort since it'll only mine at a few kHash/sec.
My thanks to fpgaminer and the other guys who contributed to the open source fpga bitcoin miner project, on which my code is based.
Anyway, I hope its of some use. Feebdback and suggestions are welcome (the project is only one week old, but I thought I'd release it as soon as I had some working code). And yes, I know its abysmally slow
