A new 1g FrSky D8 receiver is announced now flashed with firmware with working Telemetry: http://www.banggood.com/2_4G-8CH-Micro-Frsky-D8-RSSI-Two-Way-Data-Return-Compatible-Receiver-PPM-SBUS-Output-p-1119830.html
The new firmware also improves the general control range to a solid 400m which is not bad for a non-official FrSky product with non-diversity system.
