That is not what a p-zombie is. The p-zombie does not have any qualia at all. If you want to deny the existence of qualia, that's one way a few philosophers have gone (Dennett), but that seems pretty ridiculous to most people.
1. Qualia exist as something separate from functional structure (so p-zombies are conceivable)
2. Qualia don't exist at all (Dennett-style eliminativism)
But I say that there is a third position: Qualia exist, but they are the internal presentation of a sufficiently complex self-model/world-model structure. They're not an additional ingredient that could be present or absent while the functional organization stays fixed.
To return to the posthuman thought experiment, I'm not saying the posthuman has no qualia, I'm saying the red "TOXIC" warning is qualia. It has phenomenal character. The point is that any system that satisfies certain criteria and registers information must do so as some phenomenal presentation or other. The structure doesn't generate qualia as a separate byproduct; the structure operating is the experience.
A p-zombie is only conceivable if qualia are ontologically detachable, but they're not. You can't have a physicalism which stands on its own two feet and have p-zombies at the same time.
Also, it's a fundamentally silly and childish notion. "What if everything behaves exactly as if conscious -- and is functionally analogous to a conscious agent -- but secretly isn't?" is hardly different from "couldn't something be H2O without being water?," "what if the universe was created last Thursday with false memories?," or "what if only I'm real?" These are dead-end questions. Like 14-year-old-stoner philosophy: "what if your red is ackshuallly my blue?!" The so-called "hard problem" either evaporates in the light of a rigorous structural physicalism, or it's just another silly dead-end.
You have first-person knowledge of qualia. I'm not really sure how you could deny that without claiming that qualia doesn't exist. You're claiming some middle ground here that I think almost all philosophers and neuroscientists would reject (on both sides).

These are all legitimate philosophical problems, Kripke definitively solved the first one in the 1970s in Naming and Necessity. You should try to be more humble about subjects which you clearly haven't read enough about. Read the Mary's room argument.
