i previously had lehto's 800 mhz kernel before updating to 1.2

since ive flashed pr1.2 i cant handle how slow the phone is at 500 mhz

i want to install titan's kernel-power package, but if i try to install kernel-power-settings or kernel-power-flasher from extras, i get: 'unable to install, conflicting application packages.'.

Details say they conflict with following packages:
kernel-modules-maemo
kernel-flasher-maemo
kernel-maemo
kernel-modules-maemo
kernel-maemo
