Well, I did test whether the compiler supports athlon. At least it doesn't
complain about it. I get an error message from gcc -march=foobar, but not
gcc -march=athlon. This was even before the upgrade to RH7.2. Could be
that RH patches the compiler to support it? The kernel mailing list
postings I found all argued against using k6, as i686 is much closer to
athlon capabilities.
