Thanks for the prompt response.  AMD is familiar with the
need to code upstream as early as possible, no worry there.

An updated version of the patch is included in the 
2.6.23-rc3 kernel and should support all future AMD
processors, but it's a fairly large patch.  The
patch I intend to to submit is much smaller (~10 lines)
but only supports family 0x11 and earlier processors.

I'll submit the small patch for inclusion in 7.10,
and let Hardy take the larger patch for free.
