Agree with Sascha r.e. finding some place of interest.. I'd say:

I suppose this depends on what you are trying to learn first -

if you are wondering about generics of how the kernel runs processes, 
threads, handles system calls, etc, Personally, I'd take a look at the 
VKERNEL code -

/usr/src/sys/platform/vkernel/

As it's fairly simple to understand the bootstrap, without worrying 
about so much of the hardware-specific booting (such as bus device 
enumeration, etc)

If you're trying to write a new device driver, this might not be so 
helpful - in which case I'd check out the appropriate bus drivers first 
(e.g. pci, etc)

And do yourself a favor and fetch a copy of cscope. Just trust me on 
that one :)

Good luck!
