With the Linux 2.6.29 kernel
a new logo was introduced
to raise awareness for the Tasmanian Devil, a small animal nearing extinction. This interim logo was called Tuz while the traditional Tux penguin had "went on vacation", well, with the Linux 2.6.30-rc4 kernel, Tux has returned.
Besides reverting back to the Tux mascot, the Linux 2.6.30-rc4 kernel has a variety of fixes ranging from supported architectures to drivers. When it comes to Linux graphics, the DRM for the Intel i915 driver has been updated with a few small fixes along with support for the Intel G41 Chipset.
