Phoronix: Radeon HD 4550 Not Yet Open-Source Friendly
Last month we had looked at the ATI Radeon HD 4670 under Linux. This graphics card had worked just fine with the Catalyst Linux Suite, but when using either of the two open-source ATI drivers there were problems with the DVI connectors. While using an analog VGA connector works if you are just after mode-setting support, the R600/700 GPUs still lack 2D, 3D, and video acceleration using any non-Catalyst driver. Sapphire Technology though has sent out an ATI Radeon HD 4550 512MB GPU to see whether this sub-$50 USD graphics card plays nicely with the xf86-video-ati or xf86-video-radeonhd drivers.
