Oh come on, that'll buff right out.

Seriously, sorry to read of your misfortune. I think about this happening every time I haul my bike around in a rack. Can you take the bike to a dealer? My guess would be that they will "pronounce" the frame (meaning: tell you the same as the poster above) just to be on the safe side. I could be wrong, though, and I hope I am.

There are many threads here on BF regarding dents, and there's this.

I hope there is a happy ending here.
