I have connected my Atom netbook to a big monitor, and it handles
perfecly the FullHD resolution. Gnome full mode works fine and fast.
Its an Atom N450, graphics are recognised as N10 or Intel(R) Pineview GM.

All this with the monitor as the _ONLY_ monitor active.

If I try to use it on a multi-monitor setup, X gives a message about non-tiled
framebuffer and gnome-shell is slooooow as hell, unusable.
Probably that is a hardware limit, or a bug, because it happens even if
the external monitor is a projector at 1024x768.

I was wating to do more tests to submit a bug....
