An easy way to do this would be to take downtime, boot the computer
into single user mode, partition the new drives the way you want them
(i.e. /usr, and /var'), and then tar-copy the contents doing something
like:

cd /newusr
(cd /usr ; tar cvpf - .)  | tar xvpf -

then add the new "/usr", and "/var" partitions to your fstab, and reboot.

If it all seems to work, then boot into single user again, make sure
"/usr", and "/var" are not mounted, and then rm the contents of the
old directories.

You could also look at LVM to make sure this kind of thing doesn't
bite you in the future.
