I tried hibernate and suspend. Hibernate do not allow me to wake the computer, I have to reboot.
Suspend works great but no sound at all.
For the question regarding DSDT, no, I did not have to patch anything to have "deep" activated.
And my Brightness key work out of the box (as all the special keys, volume, mute, mic mute, plane...).
