Godswill,
You have a layer 3 to layer 2 mapping applied to the ATM
interface with the map-group but you don't have an IP address assigned.
This means your mapping is doing nothing.
With PPPoA, IP is running over PPP which is running over ATM.
As far as IP is concerned it is a point-to-point link and there is no
layer 3 to layer 2 mapping needed. The map-group is only needed when IP
is running directly over ATM on a multipoint interface (physical or
multipoint subinterface).

Zuke,
I do not see anything that would prevent you from doing that.
The map-list/map-group command allow you to map the atm layer 2
information
to layer 3 information of the remote atm device/router.
Remember that, you still have to define your layer 2 information under
the
atm interface, and that is where the virtual template/ppp will come in.
eg:
map-list atm1
ip 1.1.1.1 atm-vc 1 broadcast
!
interface virtual-template1
ip address 1.1.1.2 255.0.0.0
ppp authentication pap
ppp pap sent-username nnnn password xxxx
!
interface atm1/0
no ip address
map-group atm1
atm pvc 1 1 201 aal5ciscoppp virtual-template1
