I'll be sending out new cpufreq patches to the mailing list soon, will add you to the CC list. Right now you could find all the patches in the grate-driver's kernel github [1]. I don't have anything specific to test, although maybe T30 memory driver and T20/30 devfreq support are interesting for you to try? Please let me know if you'll spot any problem or have any question.
