But does that really matter here? We don't fear the user will suddenly swith
off the machine when autodetecting, we fear that probing some ports/irqs/...
will hand the machine. This probably won't effect the final processing of
the writes as long as the CPU and bus have done their work.


Plug-and-Play is really nice, unfortunately it only works 50% of the time.
To be specific the "Plug" almost always works.            --unknown source
