I've NPE-G1 with 3k PPPoE & PPPoA and it uses only 40% CPU.
It seems that you use 58% of the 80% CPU usage for ACL only if I'm not wrong
May be you can check your config about this ?

I've got a 7206VXR with NPE-G1 configured for PPPoA termination, we recieve
the VC's over an STM-1 and terminate them into various vrf's (for VPN) or
into the global routing table (for internet).
We are currently experiencing high cpu load (>80%) and some slow CLI access.
We have about 2500 sessions on the box using up to 120 Mbit @ 30k packets/s

CPU utilization for five seconds: 80%/58%; one minute: 84%; five minutes:
 PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process
  78   443181316-1276820381          0  6.12%  5.32%  4.89%   0 IP Input
 247   449268424 641021686        700  2.86%  3.35%  3.41%   0 PPP Events

Any idea on how we could debug the CPU usage ?

We've got another 7200 doing only routing an that never tops 15% CPU

Kind regards,
