Also, what happens if I checkpoint a process in 2.6.30 and restore it in
2.6.31 which has an expanded idea of what should be restored? Do your
file formats handle this sort of forward compatibility or am I
restricted to one kernel?

In general, you're restricted to one kernel.  But, people have mentioned
that, if the formats change, we should be able to write in-userspace
converters for the checkpoint files.  

I mentioned this because it seems like a key use case is upgrading
kernels out from under long-lived applications.
