similar problem - but there does not seem any solution.http://www.fixya.com/support/t2882248-kodak_m893is_not_turning
If the fall has bent the camera's lens housing - then I think it is cheaper to buy a new camera than to get this repaired.
I suggest - take the camera to a local shop and explain the problem and see what they suggest - if they can repair, how much that would be - and then compare that with the cost of buying a new one.
Really feel sorry for you - I accidentally dropped my Lumix TZ5 - I am lucky that apart from dents and inability to close the lens cap, it seems to be working fine.
That was the first time I dropped any of my cameras (and I am taking pictures since 1986 . . .)
