Geode is essentially a souped-up i586 architecture. It started as a
Cyrix i586 core and gradually got around supporting most i686
instructions; if I recall correctly, only CMOV and NOPL are missing on
an Geode LX. The real snafu is with NOPL, because it wasn't documented
until newer x86 models came out, even though it existed since the
i686. For an idea of the magnitude of the mess, see
(https://bugzilla.redhat.com/show_bug.cgi?id=579838) and other
documents linked to from there.
