I don't want to answer for the general case, but I can answer for 
my specific case.

My device has Intel Strataflash, which have 256 kB size of 
erase-sectors. I reserved one sector for u-boot (which is 
plenty) and 4 for linux --- which uses to be plenty in the 
2.4.21 days.

It is no longer plenty, some years ago I switched one of the 
targets to 2.6.15. The 4 sectors still were ok. Some months ago 
I switched to 2.6.24/2.6.25 and now space is VERY scarce. Just 
yesterday, when I trashed unionfs because of some misbehavior I 
couldn't fix by myself and went with aufs. Now my kernel 
suddenly became 14 kB too big for my device.

Now, tiny-linux patches are at 2.6.23, but I could still adapt a 
bunch of them to 2.6.25 and with that and some changed configs 
my headroom is now again 26460 bytes. Unfortunately, my custom 
boot logo had to go :-/
