There's two packages related to the nouveau driver with recent changes that are important for the release, the builds are:

libdrm-2.4.6-6.fc11
- two bugfixes, one critical and will result in random hangs on some systems

xorg-x11-drv-nouveau-0.0.12-29.20090417gitfa2f111.fc11
- fixes the bug which triggers the critical bug in libdrm
- framebuffer resize support (rh#495838, rh#487356, and lots of duplicates)
- technically an enhancement, however it appears that a lot of users find this
to be an important feature to have.
- all codepaths impacted by the change have been tested by me across a number
of different GPUs, and appears to be safe.
- speed up transition to gdm when kernel modesetting enabled
- was done by the CPU previously, which could take a couple of seconds previously,
and users would see their screen being visibly redrawn on some mode switches.
This change is non-invasive, only enabled when experimental kernel modesetting
is enabled, and provides a much nicer experience.

Please accept? :)
