    You have the completely wrong idea what a device driver is! XF86_SVGA
    is a device driver! gpm is a device driver (mouse driver.)
    magicfilter/ghostscript is a device driver (printer driver.) Neither
    belong in the kernel.

    Things belong in the kernel if they *have* to be there. Not otherwise.
    This implies the need for a coherent, *USER SPACE*, setup for managing
    devices. Bootup devices are somewhat a special case, of course, but
    that doesn't change the fundamentals.

    The whole design philosophy behind this. "Throw all the crap in the
    kernel, it's the easy solution."

    and that would not necessarily arouse suspicions."
