There's some resurrected hope for the kernel symbols of the DMA-BUF buffer sharing mechanism to be not restricted to only GPL drivers, which started off as a request by NVIDIA. This could lead to better NVIDIA Optimus support under Linux, among other benefits.
Recently there has been a lot of talk about Hierarchical-Z/HyperZ support for R600g since its set to provide a measurable performance benefit the open-source Radeon driver for modern GPUs. This support has still not been mainlined and there are still a few issues to work out, but at least the support is stable for the older "R300g" driver and has been around for quite a while at this point. For those wondering what to expect from HiZ/HyperZ performance boosts, here is a preview.
