I'm making a Linux-based (embedded) box running on an AMD Fusion board (Radeon 6310). The box starts up with a fullscreen OpenGL based application. The Linux kernel and rootfs are built using OpenEmbedded, which allows me to tweak a large number of parameters.
What drivers would be the best choice? The opensource drivers or the proprietary drivers? Being able to connect the box to a large number of different displays (and resolutions) is an important point.
