FYI, hacking the kernel's aty128fb driver---by removing the return 0; in aty128fb_init's PCI probe loop---I can get an aty128fb for both cards. So far, I've only gotten X's fbdev driver to work with it. I looks closer into why r128/UseFB isn't working some other time. Unfortunately /dev/fb1 (which is the one open firmware uses, BTW) has a couple glitches. First, it only seems to work in 8bpp: in other modes the screen splits into three parts: a top-left, top-right, and bottom. The bottom just has garbage, and the top-left and top-right seem to be mirrored minature of a garbaged version what the screen is supposed to contain. Second, it seems to have trouble erasing things (e.g. instead of putting up the X background grid when I move a window or even initially.) -- Jeffery von Ronne Graduate Student Information and Computer Science University of California, Irvine ** Sent via the linuxppc-dev mail list.
