This is the way I do it:

I use dnasmasq for dhcp and dns.  I put the data in /etc/ethers and / 
etc/hosts on the server machine running dsnmasq.  I run the normal- 
standard Debian-provided ipv4 client-daemons on the client machines.   
I did the usual stuff to the dnsmasq configuration files to make it  
activate the server and get the data, but nothing that isn't in the  
standard documentation.

For IPv6, I use radvd on the IPv6 gateway -- and the Debian-provided  
IPv6 client-daemons on the client machines.  This creates globally  
routable fixed IPv6 addresses based on the ethernet 48-bit MAC address  
of the client machine in the usual way.

I have not had to twiddle the configuration files on the clients at  
all.  I take them as they come after installing Debian.

When I add a new client machine, I copy-paste the generated 128-bit  
IPv6 addresses and record them in the IPv6 portion of the /etc/hosts  
file on the dnsmasq server machine.  The dnsmasq daemon is happy to  
offer those as AAAA records to anyone who asks.

I get my IPv6 service thru the SIXXS tunnel service.  They allocated  
me a globally routed "/48" address space.  I cut that up into a bunch  
of "/64" subnets.

It works for me...
