Is there any user land software to test the FPU emulation code?
I would like to be able to prove the correctness of the FPU emulation code in
the Linux kernel, and also port the test program to other platforms that
utilize FPU emulation. For example, DOS emulators like DOSBOX.

If the kernel already emulates it, you don't really need emulation in userspace, no?
