Now assume that I have installed a binary kernel, and the source. I do not 
want to compile all the modules. What are the explicit line commands for 

 CC [M]  arch/i386/kernel/cpu/cpufreq/speedstep-centrino.o

and 

 LD [M]  arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko ?

Is it possible at all?

Thanks !
