You have more than enough space to do it to.  Swap memory is not dumped, only
RAM is... typicall it is dumped to the swap partition.  In this case you 
have well more than enough.

If your /etc/fstab showed "/dev/da3s1b" as your 1.6 gig swap partition, you
would add "dumpon=/dev/da3s1b" to your /etc/rc.conf.  then make sure that
/var/crash has about 400M available space on it and the OS will take care
of the rest for you.  After a crash you can do "gdb -k /var/crash/kernel.X
/var/crash/vmcore.X" then the standard gdb kernel commands like "bt".
