OK, first I want to thank everyone for their comments and advice.
The players all wanted to resolve this ASAP, so today we got together and had a bit of a talk about the chain of events that happened and how they conspired to kill the party rogue. The clerical error *cough* was just one element in an unusual set of events, which are not all that likely to reoccur anytime soon, especially now that everyone will be watching.
Interestingly, some good has come of all of this. The campaign started more or less as a collection of dungeons strung together with a simple plot. Nobody had any real reason to continue doing this, as few players had any concrete goals for their characters. But now suddenly there's a strong motive to do whatever it takes to get the rogue resurrected! It's nice to see the players start to pull together as a group with a little direction! So I'm inclined to let things stand, for a more interesting and cohesive game.
At the risk of sounding overly light-hearted about this, the player of the party rogue has agreed to consider this a character building experience *slaps thigh* and roll up a new one, at least until the characters can find a cleric of sufficiently high level to bring the rogue back. I've tried to encourage him to try playing a character he's never done before, and after seeing the rest of the group come together ingame with the goal of getting his rogue resurrected, he's pretty keen on seeing where this goes. Also, no one particularly likes the idea of rewinding the game and replaying it with a different ending. It kind of makes the whole threat of death easy to ignore.
Finally, I've found the quote about native outsiders (FRCS pg. 18) and Tiberious was right, as strictly by the rules they can actually be raised. Hence the "native" part of "native outsider". Thanks for pointing that out!
Cheers everyone, and thanks again!
