there was a thread about compileing all the 64 bit info on emulation/ front ends/software a bit back, but other then interest i dont think anybody got any farther. I cant comment on your question but I am currently building a system and Im going to document my progress and in's and outs of 64 bit emulation. I'm currently waiting on a few parts before i start. Wish i could help more, but when you do find out (if you do) make sure you post the sollution for others! Good luck!
