Timeseal trouble

Does anyone know if timeseal runs in version 7.X? It worked in 6.X but since moving to 7.0 and now 7.1-PRERELEASE, it no longer runs. I have AOUT in my kernel, but can't make it fly.
I was finally able to get timeseal to work by adding
options   COMPAT_43
to my kernel. A big thanks to Peter J from freebsd.org for giving me that answer.
