Exactly the same happens on my EEE PC R252b.
When trying to suspend to Ram, everything is prepared correctly, but the CPU 
Fan stays on.
When swithcing the device off by long-pressing the power button, it goes off. 
When turning it on again, it starts at the same state as it stopped before (not 
reacting at all with a black screen but fan is on).
To make it work again, I have to unplug and remove the battery.

Suspend to disk: The same happens here. However, I can turn off the notebook by 
long-pressing the power button.
When pressing the button again the machine boots to grub and then restores the 
suspended session
-> it works more or less, it just doesn't turn off automatically.


To me, this doesn't really look like a GPU driver problem to me, but more like 
a screwed up ACPI implementation in the BIOS that doesn't really turn into 
sleep-mode when told.
