Uh, what FAQ?  (Yeah, we need one. 8^)

That's all.  Just put the chip in (if you want it).
However, you can run NetBSD just fine without the FPU.
All you have to do is build a kernel without FPCOPROC
defined, or patch the variable fpu_type to zero during
kernel startup.  (Someday, an FPU probe will do that.)
