Yes, I used the coderus implementation for kernel-plus, but never accepted the update. The button-which-didn't-buttoned problem was gone after an apt-get remove --purge, reboot, careful examination that I was unsde kernel-power and the mod was listed as available, and just then installed the coderus package after modprobing, and later modprobed again just tu be sure when the UI was installed.
Anecdotally, I never could OC above 1150, while my N900 tolerates perfectly fine that same number (being from factory clocked at 600...)
