Haven't we been by this before? It's not included even if you have
I586_CPU either.
See src/sys/i386/isa/npx.c, line 432:
#ifdef I586_CPU_XXX <--------
^^^
This has been disabled since r1.95, in 2001 (in 5-CURRENT days).
There may be SOMETHING about including I586_CPU that speeds things up,
but it ain't that.
