During thousands of dives with Poseidon regs in our club, 
there has been one single incident of reg freezing, causing it to free-flow. 
In that particular case the water temperature was -0.6 degrees C, and 
the regulator had been used on a previous dive, and had water in the 
2nd stage. I don't remember anybody ever complaining about excessive 
ice formation in the 2nd stage, or getting ice chunks in their mouths.

I have had similar experiences of these ice chunks from a jetstream(odin)
mainly in deep > 40m and cold < 4 centigrade, however the problem was
established to be 

1 an incorrect breathing manner by me (fast and staged), 

2 an ill serviced reg

These problems have been rectified and I have had no problems since.

Have have no connection with poseidon, but I will say this I have never
seen one freeze, and I have seen a lot of valves freeze cause I dive a 
rather infamous N.Wales quarry a lot.
Mine never froze even when giving ice, however if you have any doubts, just
put the environmental cap on the 1st stage filled with vodka or other
appropiate substance.
Good advice maybe I should take it....

Tom.

I have to go down to the sea again, to the call of the running tide
Tis a wild call but a clear call,  that cannot be denied.
