Below is a link from CCO with some details. Unfortunately, the example is not FE/GE. However, I've been using /31s on FE and GE p2p links between GSRs, 7609s, and 72xxs in the lab. IOS has been a mix of 12.0 and 12.1. As I mentioned in an earlier post, cisco did remove support for /31s on FE interfaces in some versions of the 12.1 code train.
