Yes it seems to. One worry is that if we ever fix the qemu triple-fault so it really does what you're describing and only resets the CPU, then I'm not sure your int3 is the right choice.
The other question is whether that protected-mode exit switch works in practice on qemu; it's going to come back with a lot of it's devices reset.
Right, keyboard reset (and port 92h reset) should be an INIT and not a full system reset. But that's also something that should be fixed, not a quirk to rely on...
