The FAQ claims that it does, but ISTR recent discussion about removing the software emulation. However, a search of the mailing lists, and Google, fails to show anything, so it is completely possible that my memory is playing tricks on me.

It was removed last July (src/sys/i386/conf/NOTES rev 1.1091)

We should probably update this comment then, right?

# The Numeric Processing eXtension driver. In addition to this, you # may configure a math emulator (see above). If your machine has a # hardware FPU and the kernel configuration includes the npx device # *and* a math emulator compiled into the kernel, the hardware FPU # will be used, unless it is found to be broken or unless "flags" to # npx0 includes "0x08", which requests preference for the emulator.

Taken from a recent src/sys/i386/conf/NOTES file:
