That's indicative that it's the kernel doing the populating (that is,
everything belongs to root:root). That means, mdev hasn't got the chance to
'restructure' the /dev directory (that is, rename and/or move and/or chown
devices).

Does 'mdev -s' exist in your /sbin/linuxrc? Can you post your linuxrc here?
