If some part of your brain were conscious, but it didn't output the information concerning the consciousness to global awareness, would you be able to report it?

As I see it, your vocal system is generally outputting information from your global awareness. (If it isn't, you (i.e. your global awareness) will perceive it as an unconscious verbal tic). Admittedly, we don't, as far as I know, encounter verbal tics where someone says something like "help I'm a separate qualia-having entity trapped in this vocal system", but I think the vocal system would need access to the other parts of the brain through global awareness to form that sort of thought and intentionality. 

I had thought that global awareness would be necessary to consciousness after reading (most of) "Consciousness and the Brain", but then updated towards pan-psychism after considering what conscious experiences would and would not be reportable.

Consciousness also tends to be associated with memory, but likewise if we don't remember something, we will not report having been conscious of it if asked afterwards.
