That would most likely be the GMA950, aka, integrated GPU.

plasmeh, something I've been wondering about (I also have the e1705) is does the plastic cover over the hinges (the same piece as where the power buttons are) feel a bit cheap to you (creaky when pressured, etc)?
So far, after having my 1705 for a while that's really my only major compaint as to build quality, and I'm just checking to see if other users have noticed this as well (I'm guessing the reason I notice it is because of how many times I've opened it up...)
