I think I understand now. But this is a 64-bit vs 32-bit problem not
an AMD vs Intel problem. The amd64 ISA is used on all 64-bit
processors from Intel and AMD (which is virtually all new processors).
So from what you are saying the problem arises if you have a 32-bit OS
on the backend, then you will have trouble making a diskless image for
a 64-bit frontend. However, this is also a moot point since all of
these processors work in 32-bit or 64-bit mode. That is the whole
point of the amd64 ISA, it is extension of the existing 32-bit x86
ISA. So worst case you end up creating a 32 bit diskless image for
your frontend and you experience marginal decrease in performance for
some applications and you are limited to 4 GB of RAM. Not having to
tried a mythbuntu diskless setup I can't say for certain, but from
your description this seems to be the issue.
