The kernel is already running on processor #0. It's just enabled #1. But since
you're running 2.2 on an F50, it expects to find 2 more (which it doesn't).
You will most likely have better luck compiling your own 2.4 kernel
(http://www.fsmlabs.com/linuxppcbk.html), but that will involve more work on
your part.

This is a hardcoded limit in the 2.2 kernel. Again, you'll most likely have
better luck with 2.4.
(Maybe this is a sign that you should donate some RAM to the needy. ;)
