I've a knoppix 3.6 hard disk installed in a sony pcg-fx301 which works wonderfully except that the time zone refuses to be anything other than GMT.
You can tzconfig until you're blue but each time you reboot your kde/icewm docked clock is GMT. Now, after looking EVERYWHERE and finding NOTHING I chanced upon /etc/init.d/knoppix-autoconfig that seems to tell the system that if your $LANGUAGE is UK then you automatically live in London. Some of us live in France.... The quick fix is to:

cp /etc/init.d/knoppix-autoconfig /etc/init.d/knoppix-autoconfig0
sed -e 's/London/Paris/' /etc/init.d/knoppix-autoconfig0 > /etc/init.d/knoppix-autoconfig

If anyone else is having similar problems, you might try something along these lines ...
