If it was me I'd politely point out that etch has been stable for over a
year now and that this means sarge no longer gets security updates.
Thus unless they are willing to do their own security and backporting of
patches, it can't be run safely.

It's not really a debian question as much as general linux question.

As long as the amd64 kernel has support for running the right format
(x86 probably) of binaries it *should* work. NPTL / Linux threads is a
libc issue, so you should be able to run the host on NPTL and the guest
on linux threads - given that the kernel has support for both (IIRC
Linux threads used clone(2) / vfork or similar).
