Nice to see sources getting smaller... but how much bigger do the binaries get
for someone only using ext3?

The difference in object size between ext3 and ext4 is about 200k.
Most of the efforts to use really tiny kernels are looking at kernels
way smaller than even ext3, so this isn't something I'm terribly
worried about.  (That is, they'll be using ext2, or squashfs, or
jffs2, etc.)
