    Perhaps you have a pointer to a git repository with your changes
    that I can clone from.

    I can make sure the LX60 and LX200 didn't break. We have a
    number of bug fixes and new support for SMP and a new MMU
    that we expect to ready for prime time soon. I'd prefer to
    use git to test your changes and doing the merge.

    How about I add accounts for you, Oskar, and Daniel and
    we use the repo(s) as a staging site to test each other's changes
    before passing them upstream to Christian and Linus.

    It you don't have an external Git repository you could just
    ftp a copy and we can add it easily.
