Cisco WAN :: Does 6500 Not Have Hardware Redirect / Rewrite Capability

I am configuring a WAE-7341 for standalone content engine ACNS used for webcaching only.When I enable the l2-redirect and l2-return on the WAE I get high CPU on my Cisco 6504-E with  WS-SUP32-GE-3B - WS-F6K-PFC3B. The 6500 shows the wccp status as L2 for redirection and return and webcache works but this CPU spikes to 70%. [code] I don't see which process is causing this but if I remove WCCP from the interface, it drops to 1% so I know for a fact that WCCP is causing this.
 
If I remove the l2-redirect and l2-return on the WAE, WCCP on the 6500 registers GRE for redirection and return on the 6500 and CPU drops to 5%.If I enable the "wccp webcache accelerated" option on the 6500, I cannot get WCCP up with or without the l2-return and l2-redirect options on the WAE, it displays: [code] does this 6500 not have the hardware redirect/rewrite capability? My WAE is directly connected to the 6500  WS-X6548-GE-TX blade on the same vlan that I am doing a wccp redirect on.
