With QoS disabled you basically have a FIFO queue that is tail dropping all traffic it does not have buffer space for. If you run out of buffer spaces on a non-virtual interface, they will appear as output drops.
show interface | i drops|line
With QoS enabled you can actually look into drops per hardware queue with:
'show queueing interface gx/y'
6500 is a hardware forwarding platform, packets are switched too fast to be able to monitor queue fullness, which is why you will almost always see 0/2000/0/0 (on a L2 interface) where the first 0 is packets in queue. So drops is really the only indication of congestion.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
