Eric Norum interfaced this package to RTEMS and I have merged it with the
"bleeding edge" source.  I am sure he will correct me if I am misreading
the code but it appears that essentially all that was required was to
install the FPSP exception handlers in the vector table.  If you are using
an RTOS, then you might have to do something special to avoid having the
RTOS do any processing for these exceptions.  The FPSP code assumes it is
directly invoked as the exception handler.
