I've rolled out HP DL585 (4x S940 Opteron) with RHEL3.
I'm also now running CentOS/RHEL 3 and 4 on my Athlon 64, as
well as Fedora Core 3.

Debian doesn't have an official x86-64 port yet.  I have not
tried SuSE, but the SGI XFS list is buzz with a lot of
complaints on their x86-64 release.

I've only used Red Hat Enterprise Linux 3, CentOS (a RHEL
rebuild) 3 and 4, and Fedora Core 3 on my Athlon 64 -- all
x86-64.

I have installed 2 and 4-way HP and Tyan Opteron systems with
RHEL3 prior.  Several were running Oracle for production
financial and engineering usage.

64-bit works fine for me.

My only complaint is Red Hat's insistance to install the
x86_64 Firefox package when the i386 is more appropriate
because nearly all plug-ins are still i386 -- including
HelixPlayer which Red Hat ships.
