Hi,
when you only need a automatically managed /dev (and not need udev) you
can try the first snapshots of the new 2.6.32 kernel with enabled
devtmpfs. i have tryed this yesterday (linux-2.6.31 +patch
http://www.kernel.org/pub/linux/kernel/v2.6/next/patch-v2.6.31-next-20090925.bz2)
and its works very good for me. you can mount /dev with "mount -t
devtmpfs none /dev" and you have a complete /dev managed by kernel (when
you need udev and it works, udev is very fast with this).
