Incidentally for i386 I do: cpu_reset() is intentionally not part of
cpu_init() there because afterwards the machine or something sets
whether this CPU is a "bsp" (Board Support Package? ;)) and only then
resets it.

For ppc and sparc I don't know but I'd be surprised if it's necessary
for ppc... Alex?
