Hi, we'd like to hire someone to get a modern OpenWRT on a mediatek device. I posted about it before: Ripping OpenWrt from router which does not provide firmware downloads (I now have the actual bin files from Kasda directly)
Another relevant thread: MTK-OpenWrt-3.10.14-SDK
I also have the pinouts for the boards and would be happy to send pre-tagged devices verified to work over serial, the end goal is we want to be able to run the Minim agent on OpenWRT devices and these are the most cost effective method. Making an investment in a developer to get this working makes sense in the long run. If you're interested we can talk privately via e-mail or phone.
