Обещают кучу всего полезного, особенно это касается ATI:
The Direct Rendering Manager improvements in this next kernel release will be particularly interesting and are perhaps as significant as earlier kernels that had introduced kernel mode-setting support for Intel and ATI/AMD hardware along with in-kernel memory management. The changes that the Linux 2.6.33 kernel will bring are aplenty and will impact almost all of those using an open-source graphics driver stack.
First off, the DRM in the Linux 2.6.33 kernel will finally deliver upon the KMS page-flipping ioctl. This Kristian Høgsberg innovation makes it possible for ATI and Intel hardware (along with NVIDIA hardware once Nouveau is merged) to have tear-free updating of the screen with low-latency page-flipping. This support will be worked into the X.Org Server, but it also happens to be one of the requirements for the Wayland Display Server. What this means for Wayland is that now any Linux 2.6.33+ kernel built from the mainline sources will be compatible with this radical display server and that no extra patching is required, but sadly some separate code branches and other hurdles still need to be overcome for other system packages.

Turning to the ATI/AMD side there are even more changes — in fact, the ATI work makes up a bulk of the DRM work for Linux 2.6.33. First and foremost, with the Linux 2.6.33 kernel there is Radeon DisplayPort support, which allows users to power their DisplayPort monitors via ATI Radeon hardware with the kernel mode-setting driver. This work is taking advantage of some of the Intel DisplayPort code that was shared earlier. Another big and important feature carried in this DRM pull request is the R600/700 IRQ support, encoder cloning support, external TMDS chip support, many suspend/resume fixes, a new new PLL algorithm for R500 chips and later, digital output hot-plug detection support (currently for DisplayPort monitors), and locking issue fixes.
