after reboot - the BIOS copied from the boot sequence, and from digging through the BIOS itself

I can't find anything else (so far) from digging round in my system info, but maybe I don't know where to look.
That's more than enough. Somebody put a copy of the manual for this board online. I can't access the whole thing, but the table of contents confirms that it supports 64-bit operation.
Maybe Felix is right about the BIOS being corrupt. It looks like ASUS still provides a BIOS file download:

How to actually flash it is another question.
What happens if you just try to boot (not install) from a 64-bit-only live CD (any distro)?
