This is a very intersting problem (for me). Because I have no
access to a computer without FP hardware, I cannot say so much
about it.

Or is there any way for me to simulate the software FPU even when
I have a 486 DX?

And to your problem with the exception. As far as I understand
the software FP software, it works by generating an exception
for any floating point code. Since it is under DJGPP not possible
(I don't know if this will fixed in the future) to debug programs
which use exceptions, you have really
a problem when you try to debug a program which uses the software
FP code.

And at last: If there is someone who can tell me, how I can
simulate this situation on a processor, which has the FP unit
on it, I would do my best to fix that problem.
