Interesting, is that ftp mounted as some hdX ?
Because DSL will only look on what it sees as locally attached media.

Is 50,490,597 KNOPPIX a directory with a 'knoppix' file in there?

Of course, you could always install to your usb drive instead.

knoppix is a file so ,
BOOT_IMAGE=knoppix

i have no idea to mount something get from tftp to hdx

Have you tried using 'toram' in the kernel parms?
