arm: let's face it

our weak 800mhz by default dual core phone is too weak to handle normal hotplugging based on load. i'm working on something new but i need the help of users to tell me:
what cpu intensive tasks do they do on their phone even when they aren't physically touching the screen of the phone?

i'll disable the hotplugging driver for now and use it only for tests.
