The issue at hand is that at least with the current toolchain, we need 
to pass -march=generic in order for these instructions to be generated. 
  We have an option for this, CONFIG_X86_GENERIC, which distributions 
really *should* be using anyway.

And yes, it should be the default.  The patch I have makes it
"default y" as well as change the help text.

Would it make you happier if this option was forced enabled unless 
CONFIG_EMBEDDED was on?
