Hi Bob,
   I managed to get it fixed with Knoppix just before your response
came in. I'm not booting into Gnome again.

   Now, I've tested the script file and it works, so it's no big deal
for me to leave it this way for a while. He'll be happy to have
wireless networking at all, even if it comes with the pain of doing an
extra command. I can probably do something under sudo to make it so he
can do it himself.

   The real question is why did it fail when the script call was in
/etc/rc.local? Is that not allowed? The header says it's executed
after all other init scripts. Can I not call a script in this file?
Maybe I have to put the command themselves in there?

Thanks,
Mark
