I tend to do similarly, but just not with entire trees like /usr, /var, 
etc.  Rather I take specific sub-dirs that:

1) are being used for data
2) are being used for custom-installed software (i.e., non distro or 
package system installed), or
3) are starting to grow very large (and threatening to use up the space 
allocated for my / partition) - e.g., the package cache

and put those on logical volumes:

/dev/sda3 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw)
none on /dev/shm type tmpfs (rw,size=1G)
/dev/sda1 on /boot type ext3 (rw)
/dev/mapper/vg1-lvpacmancache on /var/cache/pacman type ext3 (rw)
/dev/mapper/vg1-lvjava on /usr/local/java type ext3 (rw)
/dev/mapper/vg1-lvdocs on /usr/local/docs type ext3 (rw)
/dev/mapper/vg1-lvshare on /usr/local/share type ext3 (rw)
