Not sure what you're talking about - one link from the landing page
("Size" -> http://elinux.org/System_Size) indicates you need at least
384k RAM for a 32-bit 2.6 kernel running TCP. Seems pretty clear to
me.
> So any cleanup and shrink effort could be quite a large effort?
Yes; as Mike Baker states below, this size class is usually reserved
for PIC-like implementations, where the application _is_ the kernel.
It's a little larger than most PICs, but still in the same size class.

I think it is rather well documented - both in the site you link above
and in other people's posted experiments. By all means go above and
beyond that if you like, but IMHO 50/500k is just too small to do any
interesting GP computing today.
