Thanks Josu for the LED source code. It works! Turns out my basic problem with autoconf.h was my confusion with all the kernel trees I have around. I was downloading and compiling new kernels into: /opt/eldk/ but my NFS filesystem was targeted at: /opt/eldk/ppc_82xx/ autoconf.h is generated during the $make menuconfig step (I'm pretty sure), and so was placed in: /opt/eldk/usr/src/linuxppc_2_4_devel/include/linux but my running kernel was looking for it in: /opt/eldk/ppc_82xx/usr/src/linuxppc_2_4_devel/include/linux
So I downloaded new kernel sources into /opt/eldk/ppc_82xx/, recompiled, fixed some symbolic links, and did a little makefile magic to ensure the right stuff is included when I compile modules, and all now seems well.
