I am very interested in your success or failure, because my set-up
is similar.  I am using Knoppix-2003-11-14 with many updates, but 
the kernel and alsa date from the original CD.  I have a cheap Hercules 
sound card.

What works for you and what does not?

Knoppix supports alsa since April 2003.  But you do not get it
automatically; you have to pass the boot option "knoppix alsa"
(without quotation marks), even today.  This situation will
change soon, since alsa is built into the 2.6 kernel.  Knoppix
will use 2.6 as the default kernel starting in March.
