I can confirm this. Device Manager calls it ATI Rage 128 Pro Ultra TF with Bus Type: PCI (even though it's an AGP card?). Also, "Desktop effects cannot be enabled". Molecule screensaver causes total lockup. I started digging into this problem when Gwyddion (image processing program) caused lockup when trying to go into 3D view.
