    I meant the rebuilt not to use KMS, but general case. To me the kernel
    has one of the great advantage of being lots of self-consistent code
    because of being maintained in one repo + good build system + good
    development process. And as the result it is (relatively) easy to
    upgrade.

    Anyway, this is just a note from both kernel and X stranger, so
    whatever...
