I just tried linux-image-2.6.14-2-sparc64 version 2.6.14-6 on my blade 100. Console looks ok, except for some "snow" or noise when text is scrolling. Xorg still insists on 1280x960 at 60 Hz; if I lower the resolution to something like 1024x768 or 800x600, it will put the refresh rate at 85 Hz. At all of those resolutions though, there are red pixels on the screen, most notably when moving a window. If I boot the same kernel with 'video=atyfb:off vga=normal', Xorg suddenly does run at 1280x960 at 85 Hz. Unfortunately, with that parameter, my second framebuffer (another ati mach64 card) is not initialized, and Xorg only uses the onboard card. The error in /var/log/Xorg.0.log is: (==) ATI(1): Chipset: "ati". (**) ATI(1): Depth 24, (--) framebuffer bpp 32 (**) ATI(1): Option "reference_clock" "29.5 Mhz" (EE) ATI(1): Adapter has not been initialised. In summary: 2.6.14-2 & Xorg seem to work fine for a blade 100, provided that you disable the ati framebuffer (although I haven't tested it longer than a few hours). Now, if I could only find a way to make either openboot, the linux kernel or Xorg (correctly) initialize both cards...
