Only last week I had suggested that an interesting project for a community member would be to figure out what it would take to make Xorg run on OpenSolaris SPARC with a graphics device for which Xorg has drivers for other platforms, such as the PGX-series boards based on ATI Mach64 or the XVR-100 based on ATI Radeon 7000. I figured this would take a little while and a bit of work for someone to figure out. I guess I was wrong.
Martin Bochnig announced yesterday that not only had he done just that, he'd gone ahead and built a LiveCD distro using it - marTux. He's promised ISO's later this week and there's several people here waiting to see it now with high hopes.
