Given the hype generated by this Phoronix article I decided that the bloody patch (:D) was worth a try. An updated 2.6.36 kernel package is now available in our testing (sabayon-limbo) repository and will be moved to mainline in a dozen of hours.
It looks like we’re the first providing these responsiveness patches for production usage. To know how to use the sabayon-limbo repository please read our wiki.
And then install sys-kernel/linux-sabayon-2.6.36 package and reboot with the new kernel.
Attention: make sure to update your video drivers and other external modules you may have on your system before rebooting. DO NOT try this if you don’t know what you’re doing. The risk of turning your hard drive into a paperweight is close to 100%.
