Great to see your project moving on! Even though others (e.g. Intel) have now started working in this area, this should not stop you or worry you in any way: different cpufreq governors are a great thing to have -- as different users may have different needs.

Hopefully you're using current 2.6.0-testX kernels to obtain the latest source code. The patches there are for 2.4. kernels mostly, and the patches seemingly for 2.6. are a bit "behind" at most times. Good luck, Dominik
