maybe it makes sense to start including r300 in mesa. You guys have made a lot of progress. It doesn't have to be built by default, and the development can still happen in r300 cvs (just sync them from time to time), but it might help with the testing since snapshots would be made nightly. OTOH, it's still fairly experimental.
