Cisco 7500, VIP2-40, PA-TX and PA-OC3

Have anyone here pushed these configurations (Cisco 7500, VIP2-40 and PA-ATM-OC3 or PA-TX) into full line-speed (155 Mbps ATM, 100 Mbps Fast Ethernet) steady-state traffic? I was wondering if, even following the one PA per VIP guideline, these configurations will achieve a operational state or incur in packet loss. Traffic pattern is supposed to be same packets/s ratio on both sides, 100% bits/s ratio on one way, smaller packets on the other direction. Rubens Kuhl Jr.
