This is a software restriction. 12.0S and 12.2(25)S support port mode..

VXR1#sh ver | i IOS                                    
Cisco IOS Software, 7200 Software (C7200-JS-M), Version 12.2(25)S10,
RELEASE SOFTWARE (fc2)
VXR1#show mpls l2 hw-cap int fa0/0 | b Transport type Ethernet    
Transport type Ethernet
  Core functionality:
    MPLS label disposition supported
    Control word processing supported
    Sequence number processing not supported
    VCCV Type 1 processing supported
  Edge functionality:
    MPLS label imposition supported
    Control word processing supported
    Sequence number processing not supported 

I don't think 12.3T and later support port mode either, so you need to
use an S release train to do so..
