Your pre-compiled RT kernel may have the real time modules permanently
installed in the kernel.  I haven't run one that way, but I suspect it is
possible
to do it that way.  I would try the insmod commands to install the modules
that run under the real time subsystem, and see if they complain, or start
running.  I suspect they will find the correct services available and will
start running just fine.  There should be some test programs that wiggle a
pin on the parallel port and try to talk through the PC speaker to demonstrate
the RT services are working.
