So, the hardware is OK.  Next step would seem to be to test it with a
liveCD of F16.  If that works, then it is something in your
configuration blocking it. Look in /etc/modprobe.d/blacklist.conf to see
if it is blacklisted for some reason. This is a long shot.

Seems like as good a reason as any.  But why?

The kernel alsa sound docs suggest that this card is automatically
supported.

VIA VT17xx/VT18xx/VT20xx
========================
  auto          BIOS setup (default)

So it might be that the Knoppix kernel has the sound driver compiled in
rather than loading as a module, thus bypassing any module loading
issues.

You could try, as root,
modprobe -v VT17xx
to see if it will load the driver.  If it doesn't, it should give you
some errors.
