An SMI should definitely wake up a processor in halted state!
This lets OVMF boot with SMM on multiprocessor systems, although
it halts very soon after that with a "CpuIndex != BspIndex"
assertion failure.

Great, that's something I should look into then. I'll apply this and
then see what's up with the assertion failure.
Thanks!
