I tried setting up a system that way, but there are a couple of problems:

1) You have to patch rc.sysinit to fake an entry for /usr in /etc/mtab.
    That's easy enough, and not necessary on distributions where /etc/mtab
    is just a symlink to /proc/mounts.

2) You have to disable the automatic fsck of /usr.  Because /usr is now
    mounted, fsck will always fail regardless of the "clean" state of the
    file system, and the special handling for the already-mounted root
    file system seems to be hard-coded in the fsck binary and can not
    be made to apply to /usr.
