RFC 1812 was written before TOS routes were pulled out of OSPFv2 (due to
too fee independent implementations).  No one implements FIB lookup as
described in RFC 1812 in the core.  What people do implement is PBR, as
well as DSCP-based nexthop selection for MPLS DIFF-TE (RFC 3564).

What about edge?

I've seen no evidence that any HW-based router is doing this.

None of the chips i have come across had it - what about NPF, are they
putting this in their specs?

The PBR nh selection is a post routing policy though. Do you see it 
valuable to have DSCP replace TOS for lookup? 

No.  No protocol is distributing DSCP-based routes.

Ok, sounds like we can write an obituary for TOS based routing.
RIP.
