I've subscribed to freebsd-emulation & The goal is to get 2.6.16 running.

There's precedent that FreeBSD people helped companies to get a native version up and running. Either by access to the source or just based upon error logs or by answering questions. It sounds like this would be interesting to one or two ports committers (e.g. maho@ maintains a lot of scientific applications). Just in case you get someone to talk with. > If anyone can provide any guidance, it would be greatly appreciated. Unfortunately I can only tell you: if you need the 64bit version of the linuxulator, you need to write it yourself (partially, I would not be surprised if you can share a lot with the existing implementation).
