Although the tests only cover a tiny subset of HTML5 cases that IE9 supports, I like the approach. If each browser had a test suite that they passed 100% and could run against the other browsers, it would be an interesting way to move towards compatibility.

Better yet, make automated test cases part of the standard.
The pages used for this actually are test pages they developed with the W3C, which is almost making them part of the spec.
