More details to follow, I now need to build a kernel without framebuffer support to check the kernel-side dependencies. To change to an already-supported resolution, xrandr is your friend. In that example, they seemed to be adding a mode to run full-screen on an odd screen size. ĸen -- Nanny Ogg usually went to bed early. After all, she was an old lady.
