I believe that if the driver is in use, the removal of module will
silently fail. ( .... 2>/dev/null) If the second device is unsused, I
guess the module will be unloaded. For me this is acceptable since i
believe it will rarely cause any problems in real life.

I would be more than happy if it does the job "good enough". Might be we
should include this ina separate ebuild/project together with the
busybox init.d scripts?

I had a short look at your scripts and first impression was: clean,
readable, well commented shell code. Beautiful!

I look forward to test in the comming week.

Thanks a lot for you work on this. Higly appreciated!
