Overall, a migration like this should go pretty smoothly as long as people with separate /usr take appropriate actions to make sure their systems will boot. People without separate /usr can basically relax and enjoy the ride.
If a separate /usr is the only holdback, would it not be possible to simply add static devnodes to the pre-udev /dev , and make a pre-init wrapper script that mounts /usr ?
I know that the genkernel initramfs more or less does this (except that it only attempts to mount 'root' instead of /usr, iirc), but it wouldn't be hard to implement this behaviour in the main system either.. In fact, it would probably be possible to emerge a small package that would do this very thing (although getting behind a udev-controlled /dev might be tricky at emerge-time -- it would need to have a rather heavy pkg-postinst).
