apply patches. Run this. Rinse. Repeat. :-)

linux-2.2.20.tar.bz2:		15,751,285 bytes
linux-2.2.20-nbl.tar.bz2:       15,608,085 bytes

Patch Size (uncompressed):	17,815,166 bytes (yes this _is_ 17,4 MBytes)
           (compressed, bzip2):  3,322,456 bytes 

One mega-patch to shear off about 140 KBytes from the compressed (and
about 170 k from the unpacked (94488 vs. 94316 KBytes ) kernel source
would (while it may be the biggest single "reduce-size-of-kernel-tree
patch" in years :-) ) a little gross.
