The messages you get are fine ... the problem is that the version you used is 
botched. Use 2.4.26-3 and you'll be fine. Alternatively, IIRC if you redirect 
stdin and stdout somewhere else it will maybe work (use /dev/zero for stdin).

I.e.
linux ubd0=/uml/root_fs_debian2.2_small < /dev/zero | tee UmlOutput
