Tried it out yesterday and it works!!!!!!!!

Some little problems:

* the iBook's own screen is just blank

* ctrl-alt-f1 to get to the non X windows mode screwed everything up,
  I had to reset and reboot

* the iBook going to sleep screws everything up,
  I had to reset and reboot

* mac-on-linux (osx) got very confused and is still completely mixed up
  after that little experience (I have to find out how to get its
  monitor configuration back to "factory settings").

Interesting. But I will risk doing this the next time I give a
real live presentation.
