emu on N800; any experience with gtk or similar toolkits?

After someone in #9fans prompted me to notice that my file simply got
truncated, I've now got emu running on the Linux/arm-based Nokia N800.
The Inferno side just worked with a current inferno-os checkout; the
hard part was working with the Linux cross-development environment
Nokia uses (scratchbox) and getting X libraries and headers in the
right places.

The next hurdle is the fact that the default UI is all Gtk,
specifically something called Hildon. Has anyone done anything to make
inferno/wm play nicely with these types of toolkits? In particular,
it'd be nice to get their pseudo-keyboard text input method.

Lacking that, I'm going to just try and convince it to go full-screen
and use wm/keyboard, but I'm not sure how tight a hold the Gtk-based
stuff has on the screen. I'll let you know if I get any good results.
