This is a "Floating Point Accelerator" - a "homebrew" FPU that Sun used
before 68881's were commonplace.

NetBSD probably couldn't work with this too well.  m68k binaries are currently
built to assume the m68k floating-point instruction set (as implemented by
6888x and '040/'060).  Software emulation is provided in some ports.  The
bottom line is that you'd have to re-implement the software emulator to
use the FPE, and 881's are around $40 if you can find them and work much
