The Overo platforms can run X11. 

Here is a link to a getting started guide


Here is a link on how to build a standard image for the Overo using the 
OpenEmbedded system. Mind  you, this is not the GNU Radio specific one, I don't 
have the E100, but I've worked on the Overo and OMAP35xx platform for 3 years 

What you can do is to merge the GNU Radio recipe, with something that you can 
pick and choose from the X11 recipe in the standard open embedded distribution.


Once you clone the overo-oe repository, under 
overo-oe/org.openembedded.dev/recipes/images folder, you can find an 
x11-image.bb recipe.

To build a root file system image, type the following command:

cd overo-oe
bitbake x11-image

This will create a tar file in the tmp/...something.../deploy folder

I should warn you, the learning curve for learning OE is steep, and you can 
look at the Old Nabble lists for Gumstix Users on many common problems 
encountered and solutions posted for this platform.

I think I took a whole year just to figure out the whole build system. You also 
need a fast quad-core i7 system to build the images using OpenEmbedded. A core 
2 duo system with 4GB RAM can take 20 hours for an omap3-console-image. A 
quad-core i7 with 4GB RAM will do it in around 2.5 hours. I use Ubuntu 10.04 
running on a Virtual Machine on top of Mac OS X, for all this work.
