Ok, so, after much googling and reading and digesting the responses here 
and on the gentoo list,
I've decided that it is going to be much simpler than I initially 
thought, and hopefully totally painless.

What I'm planning on doing is simply:

1. cd /

2. mkdir /tmp-usr

3. Copy current /usr to temp directory

cp -ax /usr/. /tmp-usr/.
or
rsync -avHP --numeric-ids /usr//tmp-usr/

4. Reboot into single user mode

5. Confirm /usr is empty (since it isn't mounted), then

6. rm -r /usr

7. mv tmp-usr usr

8. mkdir old-usr

8. edit /etc/fstab, comment out this line:

#/dev/vg/usr            /usr            reiserfs noatime         0 0

9. Reboot

Hopefully everything comes up and just works... :)

Thanks to all
