It's no secret that ATI Technologies has had a rough time in the past delivering display drivers that met the expectations of their customers. When ATI started out producing a FireGL and Radeon Linux driver they for some time were greatly behind NVIDIA's feature-rich driver. The early ATI Linux drivers had lacked essential functionality such as PCI Express and x86_64 architecture support and was also effected by stability and performance problems -- not to mention a great deal of bugs. However, over time many of these issues have been worked out and ATI has dedicated more resources to the advancement of their Linux software, but that's not to say they have been sailing smoothly.
