Which kernel are you using? Before you start it is a good idea to do a
"make clean" to remove any artefacts left by the kernel developers by
mistake. I have had several kernel builds clobbered by this.
Have you tried the latest benh kernel (penguinppc.org/~benh) ? 2.4.7 is
claimed to be Mac compatible whereas earlier versions varied in their degree
of support.
