"The decision to stick with the Linux 2.6.32 kernel rather than
the soon to be released Linux 2.6.33 kernel for Ubuntu 10.04 LTS
that will be released in April is leading to a few more headaches
for those involved with packing X.Org and the graphics components
for the Lucid Lynx release.
"Developers have already had to back-port the Nouveau DRM that
went mainline during the Linux 2.6.33 cycle in order to gain kernel
mode-setting support for NVIDIA hardware in Ubuntu 10.04 LTS, but
now it looks like they may end up back-porting even more of this
Direct Rendering Manager (DRM) code for improved graphics support
atop the Linux 2.6.32 kernel."
