Knoppix don't come with automount? Try using it!
I had a talk with Marcelo Tossati (2.4.x kernell mantainer) and ask if it was going to be part of the new kernells, so for short he say that supermount was a hack an it is best to use automount.
We used to compile Kernells only to patch supermount inside and it is a lot of work, and Automount looks like don't need all this.
