Punkbuster and performance, question/idea

Been alot of talk lately about BF and Punkbuster and the performance
related issues that come with PB.
A thought that came to mind, which was an issue in older games and
Linux/Unix servers, was the process polling timer setting in the
kernel. The default from forever(?) up through 2.4.xx Linux kernels was
100hz. Back in the Unreal Tournament days we used to recompile kernels
with this setting changed to 1000hz instead, which reduced kernel
latency by a noticable amount (10-15ms), allowing for higher "tickrate"
settings on the game server and noticably improved responsiveness for
each player regardless of ping.
How does the BF server work with the system timer? Would this setting
help for BF as well? Or does the BF server/engine have a hard-coded
"tickrate" that wouldn't be affected by this?

Anyone tried this?
What about process priority? Anyone tried manipulating it to see if it
helps with overall performance?
