I run CentOS 5 (kernel 2.6.18) and Fedora 6 (2.6.20) on my MythTV
boxes. CGROUP_SCHED and the other options appear to have been added to
the kernel in 2.6.24, so it's not an issue for me, fortunately.

It definitely was an issue for Ubuntu (and thus, I presume, Mythbuntu)
users earlier this year, especially multimedia-using ones; see

the whole tragic/sad story.
