KNOPPIX 5.3.1 has a bad r8169 kernel module that cases a kernel oops (a known bug that has been fixed in the kernel). It would be nice to have a module-blacklist option at the kernel boot prompt. Ideally, modprobe should have something like this built-in, but it doesn't. A simple solution would be a script to generate modprobe config entries from examining the kernel command line. SuSE supports this with "brokenmodules=name1,name2,...". I can try doing this with a knoppix.sh file, but I think some modules are already loaded by the time knoppix.sh is run.
