RADEON_DEBUG=notiling may have some side effects and may even change behavior of other bugs. That patch was just a guess of mine. But you have an RV350 GPU so the patch won't help you, it only makes R350 be considered as RV350-based with regard to tiling.
But RADEON_DEBUG=notiling does help without GLSL. With this option Nexuiz renders everything properly on my settings. Without this option on RV350 I have textures corruption like Gerwin on R300 so there's a problem with tiling on my RV350 with r300g. I haven't noticed any other side effects of this environment variable, yet but I haven't done much testing. The textures disappearing problem looks the same with this variable set or without it when I enable GLSL in Nexuiz and in Blur with KDE 4.5.1.
