If you have a MC68882 inserted in your TT, NetBSD will use it (and will
thus never use the emulator). So, just comment out all FPU emulation in
your kernel config. It is only kernel bloat in your case.

The people with a 040 or 060 will always need some kind of emulator support
since motorola removed some FP-operations from the CPU that need now to be
emulated in software.

On the Falcon you sometimes need FPU emulation support since the Falcon
was originally sold without FPU. I don't think any TT was ever sold without
an FPU.

Hope this helps,
