I never have bothered too much trying to find a decent FPU emulator for my old 486 Sx, but it's a good idea, at least in theory. Most apps I use don't really need it though. And for DJGPP stuff, there's always WMemu (more accurate than the default EMU387.DXE).

However, it might be easier (more practical?) to just implement a fix for the FDIV bug on Pentiums < 120 Mhz. Granted, I don't have one, but I did search for quite a bit trying to read up on it (sounds interesting, at least):
