Unix Test Port

One more question-
 I'm finally getting around to looking into producing a port of rtems to the 
ATmel AVRmega chipset.  Looking on the website, I see that the documentation 
on the site is 2 years old, or so...  Is that the documentation I should be 
going from for producing a port based on the 1007 snapshot, or should I be 
using something else?
