iWMMXt is present on Intel XScale PXA27x processors, which are ARMv5TE. This
line of processors is still being sold by Marvell. Both that one and the
PXA320 still have iWMMXt. Also, it appears that recent Marvell ARMv7 chips,
like the Armada (a.k.a. "Dove"), also have the technology, though I am not
