[PlanetCCRMA] Kernel compilation

[Luis Garrido]

Hi all!

I am considering the possibility of building a custom kernel for my 
Planet/FC3.

I have a Pentium M laptop and I have obtained very good results in Windows 
XP of undervolting the CPU. Undervolting means running the CPU at a lower 
voltage than that recommended by the manufacturer which results in lower 
battery consumption and lower fan noise. On the other hand, the stability of 
the system may be compromised, so one'd better be careful and read a lot 
before trying it.

In Windows you have utilities like Centrino Hardware Control that allow to 
tweak the CPU on the spot. In Linux, the only way so far is to change the 
voltage/frequency tables at the kernel source and recompile the kernel :-(

>From a recent post of Mark Knecht about kernel compilation (thanks!)  it 
seems that he is using a vanilla stock kernel plus Ingo's patches. Is that 
right, Mark? Is there some potential pitfall in not using a Fedora specific 
patched kernel? If you don't need dripping bleeding edge features, wouldn't 
it be safer to rebuild from the SRPMS at
