Bewan IAD A2100N (Elisa Kotiboksi ADSL2+) support?


I have an extra Bewan IAD A2100N and I wonder if it is possible to put LEDE into it. The previous Elisa Kotiboksi (Arcadyan ARV7510PW / Bewan Ibox) is supported by OpenWRT. But I've never heard anything about this.

It has a b/g/n wifi and 10/100 Mbit 4 port switch. The power supply is just 12 V and 1 A, therefore one should not expect to do anything miraculous with the one USB port. There are no visible screws, so I need to figure out later how to get inside.
