I have kernel power and updated to pr 1.3 ota without any problems. I did disable extra devel and extra testings repos to free up some rootfs space.

After installation the kernel power did 'nt work so i did a reinstall as the kernel power wiki says. http://wiki.maemo.org/Kernel_Power#U...ng_to_a_new_PR

Seems to work good with overclocking. Runnig at 900mhz now and no problems.
