Radeon Gallium3D PCI Express 2.0

For a future article on Michael Larabel's Phoronix.com looking at PCI Express 2.0 (PCI-E 2.0) performance when using the open-source Radeon driver stack (latest Linux kernel Radeon DRM, Mesa 8.0 R600g Gallium3D, xf86-video-ati Git DDX) and toggling the radeon.pcie_gen2 kernel module parameter on a few different ATI/AMD Radeon graphics cards with PCI Express 2.0 support under Ubuntu Linux.
