Uh this is strange, the gma500 driver should still load all fine and register that framebuffer driver. I think the only case where gma500 loads but psbdrmfb isn't set up is if it doesn't detect any outputs. I'd test these monitors with some other linux system first (they might be simply too broken), if that doesn't work you can quirk your system with the video boot parameter perhaps:
