Four kernels? Hah! I see your four kernels, raise you two per hour (they're
dying quite rapidly at the moment) AND a libkvm! ;-)

Leave things where they are, and just don't mount a partition on /usr.
All "being a USR partiton" means is that the (first such) partiton
becomes sdXg, and that the installer will make an fstab trying to
mount it on /usr (I could be wrong on the last point).

I have my second partition (sd1e) mount n /y1. /usr/local is populated
with links to /y1/usr.local/ directories. It keeps / cleaner. Also,
everyting (in /, including /usr) fits in ~100 MB.

Take care,
