A kitchen-sink kernel might take up that much space, but you can build a
minimal embedded kernel that only takes up ~200k, at which point 2.6k
represents a >1% decrease. Add a few more changes like this, and those
decreases start to add up. At this point, no one thing you can chop out
of the kernel will give you a 100k decrease by itself; you need a pile
of changes like this one to do that.
