I chopped the two resistors that allow it to work in an MDD, it worked fine for OS X. I still don't have working DRM, however glxgears actually shows the gears. One to two frames are emitted before the card crashes and loops in drmCommandNone. Turning on dev.dri.0.debug=1, I'm seeing an ioctl completing and returning '35' periodically. Not sure what a positive return value means, or what ioctl is being called (I assume it's a flush or something in drmCommandNone). So I'm starting to think it's the MDD that's the issue, but I'm not sure why. I tried adding the 2x_reset quirk in agp.ko, even though it seems unecessary and Linux has no 2x quirk for this chipset either. Doesn't U3 have hardware byteswappers or something...? Matthome | help
