Hi, John.  Thanks for the info.  I might be able to fix this by having a
dummy call from ieee12844pp.c to some function in parport_probe.  It
wouldn't even have to be executed, as long as the external reference is
enough to make modprobe realize that ieee1284pp.o requires parport_probe.

Keep in mind that the peripheral needs to be connected and powered on before
parport_probe is loaded, so one should be careful about forcing these
modules to be loaded at boot time.
