Look at pulseaudio.desktop and start-pulseaudio-x11. These do exactly 
that just now.

The script would need modified for this use case (as it registers X 
session handler too, not just the publication) but in theory, just 
running start-pulseaudio-x11 on each display should get you the 
necessary gubbins loaded (albeit one of session modules will fail to 
load, but you can probably just ignore that - the error is suppressed
