Nice.  Thanks for the MiriadCoin tip.  I have the hash algorithm blocks for a kein or Miriad FPGA miner, but I'm missing the little details like what the initial header fed to the hasher looks like, how the different hash ins/outs connect together (Skein is 512 bits and SHA-256D is 256 bits), if there's anything unique about the difficulty/target calculation, etc.  Any advice on where to find these details?  I've picked apart source code for other coins before for these details and would rather avoid that frustration if the details are available in a more user friendly form.
