About ZFS and RAM ...
I am using ZFS on my home storage box with Intel T8100 CPU and 965GM MiniITX motherboard along with 1GB of RAM. I have 2 x 2TB Seagate Low Power drives put together in ZFS mirror for storage purposes, everything under control of 64bit FreeBSD 8.2-STABLE (amd64). I share that 2TB ZFS pool over SAMBA/NFS protocols to the local LAN/WLAN and even use that box as a server (converting various video formats using FFMPEG and so) ... and everything is stable as rock, You definitely do not need a lot RAM to use ZFS with FreeBSD, also do not ave any 'manual' limits set in /boot/loader.conf, only modules loading:
... and ...
But its true that the more the RAM the more ZFS shines
