The main difference between i386 and x86-64 smp boot up (among a lot of quirks and workarounds in i386 that x86-64 doesn't have/need and some trivialities) is that x86-64 follows the standard hotplug state machine and i386 doesn't.
I would suggest that if you want to unify you convert i386 over to the new state machine first because that is the key difference. Everything else after that is relatively simple. You can probably pattern that after the original changeset who did this for x86-64.
The reason I never attempted this myself is that i was too worried about regressions on old machines for i386 (this code is partly very fragile) You'll likely encounter that problem. Just make sure to keep a stable email address for some years to handle the fallout.
