3D overload

Actually, at least initially the 3D hardware was there, just not validated during production (probably that's cheaper than actually removing the hardware). So with luck it might work at least to some degree, but if it breaks you get to keep both pieces. The X.Org radeon driver currently disables all functionality using 3D hardware by default on these cards but it can be enabled via xorg.conf options for giggles (the extremely low video memory bandwidth probably precludes any non-trivial 3D usage anyway).
