Thanks, with float textures it now correctly reports OpenGL-3.3

However more ugly things are going on.

When running the PBO texture upload benchmark at available at
http://www.songho.ca/opengl/gl_pbo.html, I get tons of the following messages:

radeon: Failed to allocate a buffer:
radeon:    size      : 4194304 bytes
radeon:    alignment : 4096 bytes
radeon:    domains   : 2
radeon:    flags     : 4
radeon: Failed to allocate a buffer:
radeon:    size      : 4194304 bytes
radeon:    alignment : 4096 bytes
radeon:    domains   : 2
radeon:    flags     : 4
EE r600_texture.c:1346 r600_texture_transfer_map - failed to create temporary
texture to hold untiled copy


later on, when I try to resize the benchmark window, Xorg segfaults:
