I am successfully running the dynamic tick patch on an old IBM ThinkPad A22m. When I enable the APIC support console beeps, you know bash -c 'echo -e "\a"', takes a REALLY long time to finish. I'm assuming this is a badly written program and not a kernel problem. Correct?
BTW: how do you know what HZ your machine is running at?
