Part of the complicated image probably harkens back to early ATM campus applications, pre 100BaseT.
As you mention the configuration of ATM is very similiar to frame though you need to shape your ATM traffic assuming a non UBR PVC or your "goodput" will be unacceptable. For whatever reason Cisco does not take into account the ATM overhead when calculating your shaping parameters, i.e. if your shaping a 5M pipe subtract %10, police at 4.5M for aal5snap. Now LANE I think is primarily where ATM configuration/ especially troubleshooting fear comes from, just say no to LANE! If you simplt want to extend a few VLANs over your ATM and you have LANE cards and an RSM/MSFC you can bind the PVCs to the VLAN to extend a VLAN/s across ATM.
