How do I change kernel settings to enable PWM on BeagleBoard xM?

Hi,

I am trying to enable PWM on the BeagleBoard xM. There is a very good tutorial at this link http://elinux.org/BeagleBoardPWM on how to do most of this. I have followed that tutorial, but I am still encountering a problem when I run the code. In the tutorial it states that I need to recompile the image with the kernel setting CONFIG_OMAP_RESET_CLOCKS disabled. This seems like it should be pretty straight forward and not too difficult, but I am having trouble figuring out how exactly I do this. Can anyone explain to me how I can do this, or point me towards some sort of tutorial that explains it well?

Thanks for all your help!
