That would have been good to know a couple of days ago; I shouldn't be so impatient!

My whole point in installing XP64 on this machine was a PCI wireless adapter that I can't find Win7 64 drivers for, but after 3-4 days of loading OS, updating, installing drivers, restarting and repeating - the process wore me down. It was obviously a Windows XP64 issue, so I scrapped it and installed Windows 7.

Everything is running fine now (except the wifi adapter, of course).
If there is a VISTA driver available, that should work with WIN 7. (My guess is that you have already tried that. )
