Good.

Less work for me if someone at Debian was kind enough to make a kernel
already. :)

Of course (I was planning to take a --get-selections from the current
Xeon doing the job, taking my own packages out, then running a
--set-selections on the new Opteron kit - that way I'll get the
build-deps, but of course they wont be 64-bit - that small matter had
escaped me.)

If I just used a 64 bit kernel, and kept the rest of the system
tracking 32-bit packages, would I still see stronger performance than
an equivilently specced Xeon system?

Your help is very much appreciated.
