In case you missed it (or didn't want to watch the four-hour broadcast on your DVR):
-Jaromir Jagr carried the Czech flag. His pants were undescribable.
-Aleksey Morozov carried the Russian flag. I know only KHL/European players could make the opening ceremonies...but doesn't Sergei Fedorov seem like a more apt choice for this?
-Ziggy Palffy carried the Slovakian flag.
-Peter Forsberg carried the Swedish flag.
-Wayne Gretzky and Manny Malhotra's brother-in-law (NBA player Steve Nash) were involved with the torch-passing and cauldron lighting, though mechanical problems caused them to just stand there for a few minutes. NHL.com has a small slideshow of Gretzky's involvement.
Update: NBC's Olympic website has a three-minute montage of countries walking in. You can see Forsberg and Jagr in it. NBC also has the opening ceremony in its entirety online, and this part of it has Gretzky -- just fast-forward to the 1:22 mark.
Update 2: NBC's Olympic site also has a slideshow of hockey players as flag bearers. I missed former NHLer Ville Peltonen carrying Finland's flag.
Correction: Wrong terminology in the Steve Nash/Manny Malhotra relation -- I've corrected it to brother-in-law, not step-brother.
