cd /usr/obj/usr/src/amd64.amd64/sys/GENERIC
ls -l kernel /boot/kernel/kernel
ls -l modules/usr/src/sys/modules/zfs/zfs.ko /boot/kernel/zfs.ko
cmp modules/usr/src/sys/modules/zfs/zfs.ko /boot/kernel/zfs.ko

The kernel should be *older* than zfs.ko and both instances of zfs.ko
should be identical.

One other thought is to manually do

kldload opensolaris.ko zfs.ko

In single user mode before using zpool. I have

opensolaris_load="YES"
zfs_load="YES"

in /boot/loader.conf but you may not want to add those until you know
zfs works.
