I ran the update script for my sidux install yesterday - I noticed the new kernel that was installed as part of the update. uname -r
tells me that it's this kernel now
If you wanted to try it, then you'd have to download and burn the sidux iso, which then works as a "live" CD or you can install it directly (you'd have to then do the updates to get the latest kernel, the current ISO doesn't have it yet AFAIK). All the info you'd need can be found here
Or if course, if you don't fancy that approach, then you can always just spend a couple of hours digging through distrowatch to see who's using what kernel wise.
