So far, it looks good.

I tried it in a VM with 10.0 first (to see if it actually still boots)
and then applied it to the production-server with 10.0.


Thanks a lot for all the work you have put into this.
I really hope this will end up in a release at some point, so I don't
have to rebuild the kernel (and patch the source) every time a kernel
update gets published and can get back to freebsd-update.
