LINUX KERNEL --
The Direct Rendering Manager code in the Linux 2.6.33 kernel has received many improvements including the KMS page-flipping ioctl, DisplayPort monitor support for ATI KMS, R600/700 interrupts support, support for unreleased Intel IGPs, and many other changes. Coming after this initial pull request was also the Nouveau DRM driver and VMware's vmwgfx DRM driver. The graphics fun for the Linux 2.6.33 kernel though is not yet over.

We still may see power management patches for the ATI kernel driver arrive in time for 2.6.33, but being called for a pull into the mainline kernel this morning is the long-awaited HDMI audio support for the ATI kernel mode-setting driver. HDMI audio support for ATI Radeon graphics cards used to be the unique advantage for the RadeonHD driver, but it's been ported to the DRM driver and will be supported under Linux 2.6.33.

Additionally, in this newest pull request are fixes for the Nouveau driver when building it and separately when running it on a PowerPC system, TTM memory management fixes, and other DRM regression fixes.
