    Subject[PATCH] modify console_loglevel from commandline
    These little patches (against 2.0.35 and 2.1.128, but should apply 
    cleanly towards later) allow changing the default console_loglevel with
    kernel parameters. These should be simple enough to include in the
    current 2.0 and 2.1 trees without disturbing anything.

    Two new parameters are added, "quiet" which sets console_loglevel to 1,
    and "loglevel=integer" which sets the console_loglevel to some integer
    from 1 to 10. This lets me quiet down the boot process of my
    distribution (as to not scare anyone) without having to patch the kernel,
    and additionally allows me to change it from LILO without including
    another entire kernel image.
