And the VRAM sizes are still a bit confusing (it's listed as 128M with 64M 'used'?)

The vram aperture size in the memory controller has to match or exceed the pci vram aperture. The pci aperture size is 128 MB, so the MC aperture has to be

= 128 MB. However, of that 128 MB aperture, only 64 MB is actually usable.
