@Kostis, I think SMP affects dual-core processors only. I tried enabling that option for my Centrino too, but I got the same error:
FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.17.14-ubuntu1-custom/kernel/arch/i386/kernel/cpu/cpufreq /speedstep-centrino.ko): No such device Anyway, could you please attach your kernel's .config file ?
