The pull request for the open-source NVIDIA "Nouveau" Linux graphics driver for the Linux 3.10 kernel
has been submitted to the DRM subsystem maintainer. While Nouveau has many shortcomings
against the official NVIDIA Linux graphics driver, there isn't much to get excited about with this new kernel driver update.
For user-facing changes in the Linux 3.10 kernel, the only Nouveau feature to potentially get excited about is the VRAM compression support
Aside from the video memory compression support it's mostly fixes that have been discovered as Ben Skeggs continues to work on NVIDIA GeForce 600 "Kepler" power management support. There isn't to much to get excited about with no re-clocking support or any other significant changes to help users of this reverse-engineered driver.
The merge of the Nouveau code into drm-next with the code comments can be found in David Airlie's repository
