Dave,
As you have appeared here, could you please comment why HZ was changed?

I have some confusion on this.
First, the upstream kernel has this changed (since 2.6.13 ?) in backward 
direction, i.e. from 1000 to 250.
Second, why Fedora's change is implemented just now (in the middle of 
life cycle), but not at distro release boundary?
And finally, why 1000Hz even for i586 kernel? Does anybody use i586 
machine for low-latency tasks? Or even desktop now?
