[Beowulf] OS for 64 bit AMD

I've been running FC2 on my opteron workstation for a while 
now, but I am about ready to move on to something newer.  
It has been stable, but one pet peeve I have with RH's 
multiarch support is that it ends up clobbering their rpm 
database.  It hasn't seemed to have hurt me yet, but it isn't 

If you run 'rpm -Va' on an "everything" install, then it will report 
that several 32-bit packages have binaries with wrong md5sums.
I find the following script more useful than a rpm verify to show 
the conflicts in /usr/bin:


for i in `ls -1 /usr/bin`; do
  if [ `rpm -qf --qf "%{arch}" /usr/bin/$i` == "i386x86_64" ]; then
    echo -n "/usr/bin/$i: ";
    rpm -qf --qf "%{name}-%{version}.%{arch} " /usr/bin/$i;

SuSE has a couple conflicts, but they look like oversights and 
not part of their general packaging methodology.  I haven't 
checked any other rpm-based distro.
