I guess the problem will be what network adapters drivers to include
(all or some specific), because either you need to have the network card
module compiled in or use initrd for the root over NFS. Or do you only
mean to support Sheeva adapter? Then I guess there is no problem with
adding only one or two modules.

All in all the root over NFS is a nice thing(TM). Add to it loading the
kernel and initrd images over network and you have solution that can
speed up development very much (e.g.  you don't need to re-flash the on
board memory). And probably it could be used in some emergency
situations, like when the device's original rootfs is damaged - then you
can boot over network and start inspecting.
