Thanks to everyone for their inputs.

Trying to sum a bit, I believe option 1 is best at this point:

The main reasoning for this is stability and time. We're closing in on 
releases for both PulseAudio 2.0 and Ubuntu 12.04, and stability must 
the primary focus here. I have also put some extra weight on Colin's 
advice here, as he is the one who has been the most into these issues 

Also, because this is a temporary solution, I might not want to spend 
more time than necessary on a solution, and this solution is simple to 
implement and consistent (i e, same on discrete HDMI cards and HDMI 
cards shared with analog outs).

Looking forward to future releases, where priority lists are part of 
PulseAudio core, multi-monitor experience is improving in Ubuntu, we 
might have the notifications Dennis suggests, and so on, it probably 
makes sense to do something more elegant and then revisit this discussion.
