I just tried it on a FreeBSD 8.3 system without any problems. You will
need to explain what kind of errors you had before anybody can help you.
I used a zfs volume for testing as follows:
gpart create -s MBR /dev/zvol/zpool/v/gtest
gpart add -t freebsd /dev/zvol/zpool/v/gtest
gpart create -s BSD -n 20 zvol/zpool/v/gtests1
gpart add -t freebsd-ufs -s 1G zvol/zpool/v/gtests1
gpart add -t freebsd-swap -s 2G zvol/zpool/v/gtests1
# add several more freebsd-ufs
# output from 'gpart show zvol/zpool/v/gtests1'
=> 0 41942943 zvol/zpool/v/gtests1 BSD (20G)

I also tried newfs on all the ufs partitions without problems. I just
tried this on a FreeBSD 8.2 system and it works there as well.
