So I found that the kernel works fine when compiled with -O2, but I had
a -Os in makeoptions.

That made me curious, and experiments show that a kernel compiled with
anything != -O2 crashes with alignment faults or illegal instructions.

Maybe we should drop back to gcc 3.3.6 for now as default, untill this
code gen issues have been resolved?
