I've finally got around verifying perft(10) from the starting position and it
is: 69352859712417, that is 69*10^12 nodes.

It took 85 hours for my four computers to calculate it. If some people has a
couple of spare cpu cycles perft(11) would be no mayor problem to calculate.

Hardware used:
XP2100+ (256MB hash)
XP1700+ (128MB hash) (not working on the problem 24/7)
Celeron 800 (128MB hash) (not contributing very much =))
P4 2GHz (256MB hash) (not working on the problem 24/7)
