You can get rid of an on-disk /var alltogether.
Add these lines to /etc/rc.conf:

varmfs="yes"
varsize="32m"

It will create a memory FS for /var of 32 MB (default).

You could also mount some or all of your disk partitions
read-only.  That's what I do on my embedded FreeBSD-driven
mp3 player (running from a CF card instead of hard disk),
because it doesn't have to write anything anywhere.

If you have any disk partitions that you mount read+write,
be sure to enable soft-updates because it tends to reduce
the number of physical write operations.

Best regards
