No, the console=ttyS0 is actually a prompt which asks you for possible
additional parameters, you have to type the additional root=/dev/nfs. This
is a trick in my current bootloader (which should disappear soon) that
sets "console=ttyS0" as a default command line when it can't find a
keyboard. You may append there additional kernel options.

No, it is not a kernel option. AFAIR, you could build a kernel with
default root set to NFS but network configuration parameters have to be
set either by bootp or by the nfsaddrs (now ip) kernel options.

The early part of the boot for PreP machines that I've written.

No, this won't work. I don't even remember if it is passed to the loaded
program when you select the "Network PreP boot mode enable".

Ok, waiting for you to test it.
