I can only find a mate in three...  Is this a trick or is there actually a mate in two?

Nice puzzle, but you've got the notation wrong. Other king-side castling is 0-0-0-0-0-0, that's 6 0's. Good work though.

:D

the rules were changed that the king and rook must be on the same coloumn, but i guess it's still very nice, didn't think about it!

The rook is on it's original square, however it is not an original rook.  That is the proper distinction.  As the rules were writen this was legal.  They were changed (sometime in the sixties I think) to specify that you can only castle using your original rooks.  I believe the rules were actualy changed in response to this notable puzzle by Tim Krabbe.  My only regret is that I didn't see this post in time to post the solution myself and look like a smarty pants.
