1. Create a github page where you include as much of the hardware info as you can
2. Include any custom kernel patches that you have for the hardware (I'm pretty sure this is legally required anyway because of GPL on the kernel, so this could double as fulfillment of publishing/distribution)
3. Let people go at it! Early on I expect a community leader (usually a top contributor) will emerge that you can work with to get it done. I suspect you wouldn't have to do a whole lot (beyond information sharing) to get stuff mainlined and even prebuilt distros assembled for the device!
Even if it doesn't work, it's not a big investment and it gives you a massive amount of credibility with the community.
Plus I think the Linux crowd would eat up a monitor that lets users bask in the feeling of nostalgia of a terminal with limited color.
I, for one, would love to finally work outside/well lit places using g a terminal and not having to crank my brightness
