Which counters should I believe here?

Port-channel1 is up, line protocol is up
    No. of active members in this channel: 2
        Member 0 : FastEthernet0/1/0 , Full-duplex, 100Mb/s
        Member 1 : FastEthernet9/1/0 , Full-duplex, 100Mb/s

Are the packets really being processor switched by the RSP, or are they
being distributed switched by the VIPs?  If the former, is there anything
I can do about it?  This is on a 7500 (RSP4, VIP2/50s, 12.2S code).

Also, we've been playing a bit of IOS roulette recently due to what
appears to be dCEF issues making certain IPs on our network reachable/or
not from other IPs on our network.  We're currently running
rsp-k91pv-mz.122-18.S5.bin.  We've also recently run
rsp-k91pv-mz.122-18.S2.bin and rsp-pv-mz.122-14.S1.bin.

What I need is stability with the following features:
IP
OSPF
BGP
Etherchannel
.1q subinterfaces (on the portchannel)
MPLSVPN (and tag switching, TDP, vrfs, etc.)
dCEF that works.
