Hi Peter,
Sorry for not responding right away.
Since you mentioned X Server Version 1.20.11, I did test the current code
(Version 0.6.400) with it on Gentoo Linux, and it worked fine.
If I were to guess the issue, it might be due to a rootless X Server issue.
For OpenChrome DDX to function properly, you will need root privilege.
Also, try blacklisting FBDEV related modules.
