Cisco's been known to have incorrect data in cisco.com/go/fn (which is what checked previously), but when I read the URL you provided, I get the sense that they're referring to ME3400, not cat3550....

In checking cisco.com/go/fn, I see that for me3400 12.2(50)SE does indeed provide base IPv6 features:

IPv6 Default Router Preference 
IPv6 Neighbor Discovery 
IPv6 Neighbor Discovery Throttling 
IPv6 Routing - EIGRP Support 
IPv6 Routing: OSPF for IPv6 (OSPFv3) 
IPv6 Routing: RIP for IPv6 (RIPng) 
IPv6 Routing: Static Routing 
IPv6 Routing: Unicast Routing 
IPv6 Switching: CEF/dCEF Support

However, 3550 only shows "IPv4/IPv6 Dual Stack -- IPv4 and IPv6 Dual Stack is to support coexistence of IPv4 and IPv6 networks" for any versions (44,46,etc). 

It's entirely possible that /go/fn is just way way way wrong, and that (50)SE on 3550 does have fully-working v6, but all appearances and experiences so far seem to indicate it doesn't (despite my desire for it!). If someone's got *working* unicast v6 and protocols on their 3550, please send the list a heads up!
