I seriously do not care if it's broken on OpenBSD if there is about one
user of such system. The problem is the original patch broke booting of
fitImage-wrapped kernels and this is serious breakage which makes
2016.09 release effectively useless.

I do support this revert and we will likely need v2016.09.1 unfortunately.
