Assuming that there is no significant runtime cost, why not just put this in the
default kernel? It's not a good idea to have a separate kernel for every little
feature. We have too many kernels already (creating a potential maintenance
problem).
BTW, as far as I can tell from my 2.6.35 kernel, some of these options are
already enabled (e.g., HIGH_RES_TIMERS, HPET_TIMER, NO_HZ).
CPU_FREQ_GOV_ONDEMAND should be "m" instead of "y".
