To answer myself: Yeah it runs , at least xarclock as can be seen in the picture. That was the first armel X11 application that I found in the debian archives. I'm actually thinking about trying to get Debian to properly run on the Kobo Touch, it seems that a few people already did this for the Kindle and it would be pretty amazing.

I had to adjust the Kindle xorg.conf to use the Kobo Touch RGB565 format and disable rotation, and fix a few minor things (missing directories since the init scripts weren't run and manually extract the xcb cramfs), but now I can just start X and display stuff. This opens a whole lot of new possibilities, I never realized that there was a working Xorg driver for this display.

The only thing that bugs me about this is that to refresh the display, I still need to use pickel to update the screen, thanks a lot to KevinShort for figuring this out. Look at eink_update.sh of his Kobo Weather display to see how it works.

Oh yeah and about running the Kindle software: It seems that it's not trivial to run upstart in a chroot, so that might be a hurdle. Does anyone have any idea what to do about that?
