Hi jshimmy
I have exactly the same problem with Win7x64, and I am sorry to say I can't find a solution for it. I tried everything out there, only one memory stick, disabled everything but keyboard and mouse, tried IDE and SATA drives, burnt ISO (downloaded at Microsoft) at slowest speed after checking hash code, screamed and bumped my head on the wall... long story.
I can run Win7x86 without any problem. I just wanted to be able to use more memory.
There is one thing I couldn't try and maybe you can. I think it might be a problem with Win7x64 boot.bin file. If you can create a Win7x64 ISO with Vista's boot.bin and try with that, it would prove my theory. Please check this site how to do it: UNAWAVE - Code 5 Error whilst booting Windows 7 DVD
I don't have Vista 64 to try. The boot.bin the refer there seems to be for 32bit version (I tried all that and got an error when trying to install)
Regarding your VISTA problems, I agree they look like drivers problems, let me know if the updated solved it.
