That's part of Ingo Molnar's realtime patchset, which is not present on
vanilla 2.6.10 (which is what the 2.6.10 based kernel is, mostly). If
you want the best possible latency performance and the irq tuning stuff
you should run the "older" (in the sense of version) 2.6.9 rdt kernel.
If you don't have it you can install it by installing the meta package
planetccrma-core-edge. The downside is that it does not work (yet) on
some hardware.
