The SE515 hardware is the same as the Dynalink RTA770W. In fact it is sometimes referred to be RTA770BW where B stands for Annex B but the ADSL modem can handle both Annex A and B. This just depends on the flashed firmware.

There is no running OpenWrt up to now!

But now the complete sources can be downloaded at the Siemens Homepage:
