Found it. It applied to the iLiad, which is a different architecture, and was regarding porting the 2.6 kernel to the device. But, the interesting part is that they seemed to have been willing to work with a serious developer to hook them up with a serial/console enabled device (on loan) for certain projects.
I don't know if they'd still be willing to do that, or if the DR800 is even capable of it, but it can't hurt to ask.
Here's the thread I was thinking of (almost 3 years ago, no wonder it was a fuzzy memory).
