The size of an omap2plus_defconfig kernel has increased by 760K - a 
remarkable increase that fortunately does not appear to be matched by 
runtime memory consumption.

Well let's take that back.  I seem to have glazed over the 1 to 4MB (!) 
runtime memory usage increases in boot memory consumption.  That is also 
an extraordinary increase.
