I came across the website of Xi Graphics INC. They offer professional graphics card drivers which are OpenGL 1.2.1 compliant and run on 32 bit AMD/Intel platforms utilizing Linux or Solaris 8. They tested with a Radeon 8500 128MB. Available at a special introductory price of $129 (LOL) this driver will outperform a GeForce 3 Ti500 by 30 - 50% using the ViewPERF benchmark. Update: Thomas Bruckschlegel of ToMMTi-Systems informed me that he has a quick Windows/Linux comparison benchmark utilizing the Xi Graphics drivers. Check it out! Source: XIG Radeon 8500 Driver Page
