Did you want my opteron file?  I have it
in /var/lib/sorcery/archspecs/ia32/amd and based it on the athlon-mp
changing the -march= to opteron and adding -msse2 and -m64 to the
CFLAGS.  Haven't been able to find if the HOST variable needs to be
changed or not.

Has anyone else made any progress on the lib and lib64 directory stuff?
