I did it on a 8.1-RELEASE install: I installed the system as explained in the wiki (http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot) and after some months of use, I added ahci_load="YES" to /boot/loader.conf. Device names changed from ad{4,8} to ada{0,1} and everything still worked fine, which kind of surprised me because I didn't do any labelling to my disks (I remember having done that earlier in 8.0 times, and zfs pool reported devices were unavailable, as was the pool, at that time).
