Actually I'm testing on a VIA C3 but it should be pretty similar since it
supports both MMX and 3dNow.

Perhaps the Geode does support sfence but my VIA C3 certainly does not and
according to:

  http://en.wikipedia.org/wiki/X86_instruction_listings

sfence is an SSE instruction.  (There is no "citation needed" so I assume
it is accurate.)
