Yes, it seems to be in a good form. 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.

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.

No, there isn't. The usual way it to submit new stuff to netdev
for discussion, if it is useful and of good quality it usually is
accepted.
