I was thinking it was just the kernel, but now I'm not sure... Anything 
with hand-coded assembly in it that includes a cmov instruction would 
potentially be an issue. We were talking about implementing a cmov 
trap-and-emulate function in the kernel so that CMOV-less otherwise-i686 
systems could continue to function, but nobody seems to care enough to 
do it any longer, since there's so few machines this impacts, and most 
people who'd be able to write the functionality don't have any such 
hardware to even test on...
