I looked for the same thing myself, but eventually gave up and put
together a pgn file (few megabytes) of world championship games from the
FICS ftp site.  (I also included the text of the ECO pgn data file from
the same site).  I then just crunched this through an algorithm in
my program which builds an opening book.

P.S. I could have used a lot more games, but I wanted the final
version of my opening book (with moves played only once or twice culled)
to be less than a megabyte so my whole program fits on a floppy.  Even
this small opening book seems to get my program in reasonable positions
most of the time.
