I reverse engineered the hardware by poking at these chips from the firmware prompt for nearly a week, so what's there is the best I could come up with. Using the 'fbdev' driver, Xorg should just work with the XVR2500 but there will be an ugly white boarder around the graphics screen just as the current kernel console will have. The board comes up in 32bpp mode so that's what you'll need to use in xorg.conf I cannot say the same for the XVR500 because of the funny mode the framebuffer comes up in from the OBP. So until I make some more progress reverse engineering these cards, support is still currently half-assed. At least there is some native kernel text console for this chips now. Ideally I should be able to get it to the point where dumb framebuffer Xorg support should work fully for both chips. However, I doubt I'll be able to add hw acceleration any time soon as these chips are very complicated (they use DMA commands to do hardware rendering etc.), are completely undocumented, and there's zero chance 3dlabs is going to ever release the specs for these board to help the effort along. - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
