hey, i'm working on a media box too (based on a EPIA M10000). I don't know how you plan to use the CF card but i'm going to use a IDE->CF bridge for it. In that case you can approach it as a HD and probably do a HD-install (

)), so i might be of little help. But i'm very interested in how your system and how it works out for you.
