X3100 & Suspend to ram: Screen goes blank

[wel]

Hi everyone. I recently bought a new laptop (Latitude d630), which has a Intel x3100 graphics card and a shiny new Gentoo :D

But i've some weird problems with suspend. When i close the lid, laptop goes to sleep as it should be, but it doesn't turn on. Actually, screen goes blank and, a few seconds later, shows a blurry mouse pointer. I can't switch to a text terminal, also.

Any ideas? I installed Xorg 7.2 first, then 7.3 without any changes.
