are you intentionally not setting your new ideal kernel-settings profile as the default profile? dont you have to do Code: kernel-settings default ideal to make it stick after boot? I recommend not overwriting the default ideal profile and instead place a custom-named profile in /home/user/.kernel which is also on kernel-config's search path. re: http://wiki.maemo.org/Kernel_Power#Use_of_kernel-config good work!
