When I joined Collabora last year I started to work on porting WebKit GTK to a device produced by iRex technologies based on the GNOME mobile stack and with an electonic paper display. My task was to make WebKit usable for the browser that they want to ship with the next version (with Wi-Fi connectivity) of their device, this meant adding missing features, fixing various bugs and adapting WebKit to work well with this kind of devices.
At FOSDEM I willl give a talk on what I did and I will have with me a DR 1000S, so you can play with it (I suspect that most people will follow the talk only because of the nice toy )
