http://edseek.com/~jasonb/articles/traffic_shaping/buildkernel.html#sourceopts answers this.
Kernels newer than 2.6.8 allow you to change the clock source without
editing any source files. Look under 'Networking ---> QoS and/or fair
queueing ---> Packet scheduler clock source (CPU cycle counter)'.
Keep in mind that if you use any kind of CPU frequency scaling, do _not_
use PSCHED_CPU, as variable clock speeds are not taken into account.
