Thanks to a couple offline replies, I got this working. I'm replying  
with my working config for the benefit of anyone searching the  
archives and in case anyone has any comments on something that could  
be done different/better. Thanks for the help.

On the 7206 all I needed to do was add a Virtual-Template interface  
for the multilink and point the relevant pvcs to it:

interface Virtual-Template3
  ip unnumbered Loopback0
  ppp authentication pap dsl
  ppp authorization dsl
  ppp multilink

The only line different than my "normal" template is the "ppp  
multilink" line. The reference to "dsl" is the name of the radius  
profile that I'm using.

interface ATM2/0.1000 multipoint
  pvc 3/70
   encapsulation aal5mux ppp Virtual-Template3

  pvc 3/177
   encapsulation aal5mux ppp Virtual-Template3


On the client side (1721) I have the following:

interface Virtual-Template1
  ip address negotiated
  ppp pap sent-username xxxxxxx password xxxxxxxx
  ppp multilink

The two ATM interfaces look like the following

interface ATM0
  no ip address
  no atm ilmi-keepalive
  dsl operating-mode auto
  dsl enable-training-log
  pvc 0/35
   encapsulation aal5mux ppp Virtual-Template1


That's it. I needed no Dialer interface. The two links come up, get  
bound and stay up. Is there any particular reason why a Dialer  
interface would be better or advisable?

Also the 1721 is running 12.3 mainline with ADSL WIC support and the  
7206 is running 12.4 mainline.
