Hello Yong

I don't know much about programming, but probably having a look 
into the follwing folders will help you to find the information 
needed:

/usr/src/sys/
	here is a Makefile for the whole kernel, I guess

/usr/src/sys/dev/
	device drivers which could be in the kernel

/usr/src/sys/dev/em/
	eg. here are the files of the Intel NIC driver

/usr/src/sys/modules/em/Makefile
	the Makefile for the Intel NIC kernel modul?


The chapter "II. Device Drivers" [1] in the "FreeBSD Architecture 
Handbook" [2] probably is also helpful.

Hope this helps.
