Is there any way to use these emulators on a system that has a

Hi Warner,
Without commenting on the need to have an emulator in the kernel,
doesn't -msoft-float work faster?
Yes it does. The kernel has to emulate an 80x87, giving you the
following sequence:
a) trap to kernel
b) decode FP instruction
c) fetch operands - possibly including copyin()
d)

Embedded systems, anyone?
True, but how late a version do you really want to run on them? I've left
even my P60's at FreeBSD-2.x
