Since the cpu in question is an athlon64 X2, and therefore a bit ancient,
I'd doubt that. I just looked at the initrd with a hex editor but see
no identifying text that would help to identify what I am looking at.
I'll ask on the emc machine list if there is a way to regenerate the
initrd to include the AuthenticAMD bits.
Thank you.
