Since the SUMMARY I sent out earlier I have received my first positive reply. See below.
I have not yet tried this out so don't blame me if it does not work.

Alternative to the "boot -r" is to follow these steps to reconfigure
the live kernel.
As root ..
1. touch /reconfigure
2. /etc/init.d/drvconfig
3. /etc/init.d/devlinks
This will do the job of "boot -r".
