I upgrade another system to 9.0-RC1 and encounter the same problem, this 
time zfsloader do not run.

After

mv /mnt/boot /mnt/Boot
mkdir /mnt/boot
cd /mnt/Boot
find . | cpio -pvdmu /mnt/boot

FreeBSD boot OK

[root@avoriaz zfsboottest]# ./zfsboottest /Boot/zfsloader /dev/ada0p2 
/dev/ada1p2
ZFS: SPA version 28
   pool: rpool
config:

         NAME STATE
         rpool ONLINE
           mirror ONLINE
             ada0p2 ONLINE
             ada1p2 ONLINE
ZFS: i/o error - all block copies unavailable
can't lookup

10 minutes later:

[root@avoriaz zfsboottest]# ./zfsboottest /Boot/zfsloader /dev/ada0p2 
/dev/ada1p2|less
ZFS: SPA version 28
   pool: rpool
config:

         NAME STATE
         rpool ONLINE
           mirror ONLINE
             ada0p2 ONLINE
             ada1p2 ONLINE
<blablabla>

it seems ok :-o

and a other time:
[root@avoriaz zfsboottest]# ./zfsboottest /Boot/zfsloader /dev/ada0p2
segmentation fault...

Strange isn't it.
