zroot won't mount after 9.0-RC2 -> 9.0-RELEASE upgrade

To follow-up, testkernel mounted fine using the procedure from
loader.4th(8):
set kernel=testkernel
unload
boot-conf
And the OS upgrade is now done, after a few more tweaks have been ironed
out (the most interesting of them is a difference between /boot/testkernel
and /boot/kernel, which were supposedly generated by the same 'make'
command some time apart).
Thanks again for the suggestions, all.
