If that works out, the existing or maybe a new Fennec UI should be as smooth as the new native UI of Androids Fennec (since Firefox 14 on Android).

He wrote some patches and started a WIKI entry, where he explains how to build and start it. He even points to the place of the DEB file and build instructions.

Update: Description from Romaxa:

https://wiki.mozilla.org/Embedding/IPCLiteAPI

IPC Lite API provide platform independent mozilla embedding API's, here is the test browser using that API.

All Hardware accelerated with EGL rendering backend.
Fast startup, page load, no XUL UI, Qt/QML..
On last video part of demo of browser with Multithreaded compositing (single process) example.
Binary build available here: http://romaxa.info/fennec/IPCEmbeddi...36-1_armel.deb
MOZ_ACCELERATED=1 ./qtMozQmlEmbed -url google.com

Update:
Removed my old description where I tried to get it running, as I have it running now with Romaxas lates update from 28th July 2012.

It's so much more easy now:

- download and install these .deb files from http://romaxa.info/fennec/IPCEmbedding/
libqmozembed_0.6.14_armel.deb
xulrunner_16.0a1-99370.336-1_armel.deb
- open terminal and enter these commands:
cd /opt/xulrunner/lib/xulrunner-17.0a1
MOZ_ACCELERATED=1 ./qtMozQmlEmbed -url google.com
(or any other URL)


Romaxa posted his results on his blog and published a Youtube Video! Awesome stuff so far, hell it is fast!

There is no checkerboarding while scrolling/zooming and it's smooth as butter. There is a basic UI for navigating/refreshing and entering an URL. Native VKB works there. Although it's not possible yet to interact with the content (like clicking a link).
