    I'm one of those people who *really* wants to cut down the kernel size.
    I've recently worked on a product where the kernel RAM budget is ~1M.

    I care about 5K. (But honestly, I don't actively hunt stuff less than
    10K in size, because
    there's too many of them to chase, currently).
