The HZ change doesn't make much sense for a work-conserving scheduler, the PSCHED_CLOCK_SOURCE change is there to get a higher clock resolution. > But, as the implementation is rather old, it would require a complete > overhaul for 2.6 I think.

I couldn't sleep this morning so I started to fix up the code for 2.6 ;) It's almost no work, the QoS-subsystem hasn't changed much since 2.4.3. I should be done today or tommorrow. > What is the process of getting new traffic schedulers in the kernel?

The usual way it to submit new stuff to netdev for discussion, if it is useful and of good quality it usually is accepted.
