Tiger finds the draw in 434s (7min 14s) on my K5-100MHz with 16Mb hash.
You say that computers don't know which line to compute.
OK. So load this position and try to find the key yourself:
6k1/5p2/3P2p1/7n/3QPP2/7q/r2N3P/6RK b - -
Tiger finds the key in 3 seconds on my K5-100 (with the right score,
showing that he knows that it is a draw).
I guess a lot of programs find this one very quickly too.
