SAGEMCOM fast 1704 support

Ive probably stumbled over the answer 4 times already but here goes.....I got one of the SAGEMCOM FAST 1704 adsl routers from Windstream laying around. I see support for the 2704, but not 1704. Can someone point me in a direction? Thank you.

No devices with a model number of "1704" are currently supported.

-> 1704 has only 16MB RAM, which is too little for current OpenWrt, see https://wikidevi.com/wiki/Sagemcom_F@ST_1704
