It would be a replacement for my aging web server.

HP sells a solid quad Opteron box, and if you don't require quad, the list
grows from there. But, as I said before, if you don't _need_ 64 bit, why
bother?

Since you haven't said anything about what you plan to do with this box,
it'd be silly to comment further.

But all the servers Dell offers use the EM64T. I have no choice. The port
does say "The port consists of kernels for all AMD 64bit CPUs with AMD64
extension and all Intel CPUs with EM64T extension, and a common 64bit
userspace.".

It says "compilation time optimization uses a common base for AMD64/EM64T
instead of legacy i386 cruft" but doesn't mention anything else about the
EM64T. I am not familiar with the new 64-bit technology but I will give it a
try.

In a hacking environment, cool. But for production, if you don't _need_ 64
bit, why deal with the headaches? 

If you do need 64 bit, don't buy a Xeon to run it on.

Do you want to run it as a 32 bit system?  Or 64 bit?

If you run in 32 bit mode, then it shouldn't present any particularly 
special problems.

It may be more interesting in 64 bit mode, as Debian/AMD-64 has been 
released recently...
