No. The notation of FIDE and computer chess (PGN) are not the same.

From the FIDE handbook:

"E11.  In the case of the promotion of a pawn, the actual pawn move is
indicated, followed immediately by the first letter of the new piece. Examples:
d8Q, f8N, b1B, g1R. "

And

"E12.  The offer of a draw shall be marked as (=).

Essential abbreviations:
0-0 castling with rook h1 or rook h8 (kingside castling)
0-0-0 castling with rook a1 or rook a8 (queenside castling)
x captures
+ check
++ or # checkmate
e.p. captures "en passant" "

But this does not answer Odd Gunnar's question.

I think, the e.p., promotion, checkmate and draw offer are the only difference
to the SAN used in computer chess.
