It's also possible to select hash keys such that transformations of the board's key is the same as recomputing the key for a symmetrical board position. This will be *much* faster. I came up with a scheme to do this and documented it on my website, but haven't actually implemented it yet.
I can't find your website. Can you give me a link? - Don
