Notice that the debian package has a patch which allows to have both compiled
in, and have the serial driver check that he is not on a mac before getting
enabled.
The patch is in the kernel-patch-2.6.8-powerpc, so you may have missed it if
you use kernel-source-2.6.8 directly.
I feel that we should do this kind of thing for all the legacy drivers which
poke around in random parts of the memory, and have those patches in the main
kernel-source package.
