You can boot old 2.4 based ROM's with kexecboot too. I have reports of 
success booting of Cacko e.g.

We should not update kernel while using kexecboot. We can only update distro 
(rootfs with kernel inside) in NAND.
I'm not sure that we have too much ordinary users who will flash to NAND 
instead of external SD/CF. Advanced user can boot from console-image from SD 
and 'flash' by hands according to some README/wiki instructions. Or we can 
provide special NAND-installer image for this.

But anyway having something like legacy-updater.bb is good idea.
