advantage to kickoff out of bounds, am i missing something here?

Not in Texas either (heck, I'm not even in the US) but I do work NCAA Rules.

My guess would be that Texas changed the kickoff line from the 30 to the 40 due to their younger age kickers. I'd be a little surprised if they messed with anything else.

So as ljudge already stated, the receivers have multiple options:-
o take the ball 30yds ahead of the kickoff line ie the receivers 30yd line
o push 'em back 5 make 'em kick again
o tack on 5yds from the spot it went oob
o technically a 4th option is to decline the penalty and take it where it went oob, but you would never even offer that option, it would only confuse the captain.
