Yes, athlon4 to athlon-mp are all palomino (commercially called athlon4) cored.
Unforutnately the mobile variant does not have SSE support operational,
and I don't know about athlon-xp.
The "athlon4" variant is what we may want to call "athlon-palomino" too, that
must be subset of all the new ones, so miss SSE.
