If you wanted to still be able to refer to it as /opt/local, you could make /opt/local a symlink to /Volumes/Whatever/opt/local and that should work in most cases.

The symlink was not working well for me.

I ended up doing this, with "MacPorts" as the partition name I had prepared:
$ diskutil list | grep MacPorts
   4:                  Apple_HFS MacPorts                499.2 GB   disk0s4
$ diskutil info /dev/disk0s4 | grep UUID
   Volume UUID:              D8F0DDCF-A195-3A41-8EA1-1EA7C86ED512
$ vifs
UUID=D8F0DDCF-A195-3A41-8EA1-1EA7C86ED512 /opt hfs rw,auto

Seems to be working across reboots.

I do end up with some OS X dot files in opt:
$ ls -a /opt/
.		..		.Spotlight-V100	.Trashes	.fseventsd	local
