Argh, I shouldn't have assumed that it was the full parameter. Oh well, 
on that machine, I managed to switch back to openrc. That didn't go real 
smoothly, portage couldn't figure out how to do it on it's own after 
switching profiles, it was blindly removing and rebuilding some packages 
manually that eventually made it work and not want to pull in systemd again.

After that, I was able to reconfigure the kernel without ipv6 at all... 
rebooted... and openrc Just Worked(tm) with my network issue gone.

For the other two, I'll try again but this time with the proper kernel 
parameter. That could've saved me a lot of time, but oh well.
