You're thinking with your x86/amd64 hat on here.  An ARM device can be
booted with the kernel over networking (or even via usb, as is the case
with most Android devices) and rootfs on local storage.  Just because
x86/amd64 doesn't do it, doesn't mean others can't/don't.

What exactly is missing from a stage3 aside from a kernel?  At this
point on most ARM devices, it goes like this:

extract stage3
edit inittab (and if needed) securetty
create net.eth0 & symlink it to the default runlevel, along with
openssh(assuming headless system)
copy your kernel & modules into their proper places (if needed)
put sdcard into arm device, watch it magically boot and work

What you're proposing is:
extract stage3
install qemu (assuming you don't have it yet)
mount dev/proc
chroot
emerge a-network-manager
<go get coffee, have a beer, make a three course meal>
set password (might as well, since you're chrooted)
vim inittab <oh wait, no vim, right, gotta run nano>
nano inittab (and if needed) securetty
exit chroot
unmount dev/proc
copy kernel & momdules to their proper places
put sdcard into arm device, watch it magically boot and work

Why exactly is the latter one better?  the emerge a-network-manager step
would be far faster on the device itself, even the RPi.

I plan to look into the SUSE Qemu fork, as they've supposedly sped it up
immensely (iirc it takes about a week to build gcc according to armin76
for aarch64) but even then, that would be a hack as their patches may or
may not have been sent upstream - and they may be aarch64 specific and
arm could still be slow as balls.

So remember, just because your laptop/desktop can't do awesome stuff,
doesn't mean other devices can't :)
