[Beowulf] Advantage to compiling RHEL 5 with opteron option?

[Jeremy Fleming]

Anyone know if there is any advantage to recompiling the default RHEL 5
kernel to include the "Opteron" config option on a quad processor opteron
machine?  I'm currently just using the "x86_64" version of the kernel.  If
you look at the ".config" options with menuconfig or xconfig, it shows that
the Generic x86 64bit option is selected rather than the Opteron option.

Any thoughts or experience?
Jeremy
