How about taking some directory that is currently under /var (depending on what you're doing with the machine, maybe log or www or mysql or something?) and moving the contents to /usr/obj or /usr/src (or if they're together on disk, remove /usr/obj and /usr/src and create a new partition covering the space that was used by both)? (Then change the mountpoint in /etc/fstab). If that gives you enough capacity, that might be easier than some big shuffle-around.
