I'm sure there are better and more efficient ways of doing this but this should work. And I assume this is after a HD install.
Creat a text file that begins with #! /bin/sh and follow with the commands you want executed.
Save your file in the /etc/rc5.d directory.
Make sure your file name starts with S99
Make sure it is executable by root (I believe).
It will now be one of the last scripts to be executed when your computer to boots (at least to the KNOPPIX default run level 5).

Good Luck,

Mike
