Yes, I will use the latest openChrome SVN. Should I use the latest DRM 
CVS as well (currently, I am using 2.7.4)? With the build system I have 
set up for MiniMyth, it is easy to build and run any version.

By the way, since my evenings are busy this week, it is unlikely that I 
will get to this before the weekend.
