Framed-IP-Address override NAS pool?

In my years running a dialup ISP, I used Cistron Radius and Cisco and 
Lucent NAS's.  I am no using FreeRadius and a Cisco router to authenticate 
pptp VPN users.  The default IP address pool is defined in the Cisco like 
this (parsed):

interface Virtual-Template1
  peer default ip address pool vpnpool
  no keepalive
  ppp encrypt mppe auto
ip local pool vpnpool

That works fine authenticating unix system users using this raddb/users 
config (one of the supplied samples):

DEFAULT	Framed-Protocol == PPP
 	Framed-Protocol = PPP,
 	Framed-Compression = Van-Jacobson-TCP-IP

I now want to assign a few users different, static IPs using this:

testuser	Service-Type == Framed-User
 		Framed-Protocol == PPP,
 		Framed-IP-Address =,
 		Framed-IP-Netmask =,
 		Framed-Compression = Van-Jacobson-TCP-IP

This sort of thing used to work fine with Cisco dialup NAS's and Cistron, 
even though the NAS had no pool using that IP range in its config...radius 
just forced it to override the default pool, but in this case, it just 
keeps assigning an IP from the NAS pool (and yes, I have the above 
statement ABOVE the DEFAULT statement).

Is there something else that needs to be done to allow this?

Thanks in advance!
