Ask the providers directly, it is their network thus they will have 
their own policies.

In general though, ASNs are following:

I don't know how common the strict/non-strict case is though, but 
looking at GRH (http://www.sixxs.net/tools/grh/) it seems that most 
ASN's are properly filtering, thus using the strict model.

Of course don't forget to signup for GRH if you are going to/are 
participating in the IPv6 BGP and also of course sign up to ipv6-ops to
keep informed about technical issues (SnR is quite high fortunately):
