It's actually easy. At the end of knoppix-autoconfig, a file called
KNOPPIX/knoppix.sh is searched on the CD or DVD, and if present,
executed automatically. You don't need a boot option for this.
In knoppix.sh, you can, for example, write
ln -snf /cdrom/my-scripts/45xsession /etc/X11/Xsession.d/45xsession
which should replace /etc/X11/Xsession.d/45xsession on the unionfs
system by your own version in the uncompressed part.
I added this "autoexec" feature already in very early Knoppix versions,
to be able to change things easily from the uncompressed part, without
having to recreate the compressed part, exactly for reasons like the one
you mentioned.
