System V.3 and earlier only;  V.4 will be substantially different.  VM and
networking come time mind, offhand.

This book talks about 4.3BSD.  My copy is at work, but I think there is 
very little in there that is SunOS specific.

I'd dump this one completely in favour of the AT&T Device Driver Writer's
Guide.  I understand they even have a new & improved version out.  It 
documents all the driver interfaces, kernel routines available for driver
use, includes a block & char driver (these are overly complex but it is
source), and in general is very good at the nitty gritty.  This document
does not hold your hand but will get you going if you want to write your 
ram disk driver.  *Please* don't ask me how to get one - I swiped mine 
from work.
