Subject: Computer analysis of KK game 14 endgame?

I was wondering if anyone had analyzed game 14 endgame of the Kasparov-Kramnik
match with computer programs + tablebases.  Team Kasparov claims that black
missed a win (move 55), and white missed a draw (move 46). Do computer programs
make same assessments? Here's the game:

[Event "BGN World Chess Championship"]
[Site "London, England"]
[Date "2000.10.31"]
[Round "14"]
[White "Kramnik, Vladimir"]
[Black "Kasparov, Garry"]
[Result "1/2-1/2"]
[ECO "A00"]
[WhiteElo "2751"]
[BlackElo "2830"]
[PlyCount "114"]

Here, team Kasparov gives it a "?" recommending 46. f4! with a book draw.
