Traditionally /dev was populated by MAKEDEV (in package makedev), IIRC.
umount /dev; busybox mdev -s
should also provide a locally appropriate /dev.
(mdev is part of busybox and Debian enables it, but there is not a package
with a ready-to-use mdev symlink and /etc/mdev.conf yet. Defaults are
somewhat usable, but don't have groups or permissions set as Debian
would do.)

mdev has two functions:
mdev -s will populate /dev based on what /sys says;
mdev with no arguments uses the hotplug interface, whereby the kernel
automatically runs it on hardware addition with an environment equivalent
to the contents of /sys/.../uevent.
If you disable the hotplug interface via procfs, you can use mdev -s
the way you'd use MAKEDEV.
