1. Laptop features

I've tested two similar laptop hardware.

All works after fresh feisty install (sound, ati fglrx 3D after activate it in admin system menu).

Here are some fix for suspend / hybernate and others tools/ tweaks to have a better laptop support (as ati under-clock mode once on battery).
