Suppport for Asus DSL-N17U

Hello all,
Is there any effort done for Asus DSL-N17U? I have one as a spare and like to playing around a bit. I am not that interested of xDSL side of it as I replaced it with other DSL-modem. And I got serial port communication and tftp boot working with original asus images.

However I had some difficulties found information about SoC used Ralink MT751020 SOC.

Any pointers to build OpenWrt image for this device or is this dead end by default?

Br,

AFAIK, MT7511 is not supported.
