But doesn't the `sse' present in the `flags:' field mean that my CPU supports
SSE?  And this seems sensible, since on the wikipedia page about SSE I read:

  AMD eventually added support for SSE instructions, starting with its
  Athlon XP and Duron (Morgan core) processors.

Or am I missing something?
