I'm not so worried about PCIe-based graphics, although it might mostly
work with a big of tweaking, since we can find and execute ROMs.
But for built-in graphics I would like to support it. This is a key
feature, and I hope there will be common elements. between the boards.
Similarly with things like USB, Ethernet, SD card which you have
addressed.
