But he said he wants to run it on a server.  Compiling your own kernel
is *not* the answer in a production environment, especially servers.
It's just too expensive a process.

My personal choice is RHEL5 64-bit for this application, but Fedora is
probably fine too, if you plan to upgrade every 6-12 months.

In general, though, here's just no reason to run 32-bit anymore on a
64-bit platform, especially a server.  No sense shooting yourself in the
foot by limiting the scope of your future capabilities.  I may want to
run 64-bit xen guest domains in the future, for example.  Can't do that
with the 32-bit host install.  You can, though, run 32-bit guests on a
64-bit host if you wanted to in the future[1].

[1] It's definitely possible to run a 32-bit guest distro in xen on a
64-bit machine currently, but only if you run a 64-bit kernel on the
guest.  32-bit userland works nicely under a 64-bit kernel.  The easiest
way to accomplish this is to copy a kernel, ramdisk, and modules from an
existing 64-bit xen guest, and stick it in the 32-bit guest.
