My guess would be to modify /etc/init.d/rcS from
exec /etc/init.d/rc S
to
exec numactl --physcpubind=0 /etc/init.d/rc S
(or better yet to modify the initrd)
The affinity of all subprocesses is inherrited, thus should be bound to
cpu0.
This offcourse will only function on a numa arch. But I guess smp has
similar controls.
