Yes....

!
inter eth0
ip address <public ip>
ip nat outside
!
inter eth1
ip address 192.168.0.1 255.255.255.0
ip helper-address <public_dns_ip>
ip nat inside
!
ip nat inside source list internal interface Ethernet0 overload
!
ip access-list standard internal
   permit 192.168.0.0 0.0.0.255
ip route 0.0.0.0 0.0.0.0 <gateway>


People have suggested this config will allow me to do dns queries on 
192.168.0.1 and the helper address will relay that query to the dns 
server.  So far this is not the case..

I've tried the below commands...

nslookup www.yahoo.com 192.168.0.255      <- didn't expect this to work 
but I'll try..
nslookup www.yahoo.com 192.168.0.1

Niether worked.
