No it does not. The mkboot package expects both a linux kernel and the
already packet up root disks contents. It does nothing of the composition
stuff of those scripts.

That is already in place. I did mkboot exactly because of the initrd
feature. I have tested it with lilo 19 and loadlin-1.6.

The ramdisk size in the kernel is dynamic. No need for it.

I think we can go up to 900K. That would fit on a disk together with the
kernel and allows around 2MB of effective size. The first thing a user
would do after fdisk is to activate swap.

That is what I thought.
