+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....
