Committed in r1551 (trunk) and r1552 (0.5.x branch).  It will be in 0.5.0 
final release.  This is one of those instructions which was not in the 
original AMD64 architecture but was added (I think by Intel), and then 
ported back to AMD's version.  I'm going through the instruction manual 
again, but if there's something else you know is missing please let me 
know!

Thanks,
Peter
