Hi,
First, thanks for the port. I enjoyed playing some "Broken Sword" for the nostalgy :-)
I just updated the Nokia N800 to Diablo and it seems there is no version of your ScummVM port for Diablo yet...
So I searched the net a bit and read that there is a patch (i.e. the port) in the upstream ScummVM now. Does this mean this will be autobuilt with mud-builder in the future (or otherwise autobuilt) or am I reading too much into it?

For Diablo you can install it by directly clicking scummvm .deb file from any repository. So far there is same binary for OS 2006,7, and 8. http://repository.maemo.org/extras/pool/chinook/free/s/scummvm/
As for autobuilder - yes in theory, unfortunately scummvm has quite a lot of dependencies so it is not exactly trivial and I prefer spending time on improving real code than debian packaging of dependencies. See also http://www.gossamer-threads.com/lists/maemo/developers/38141#38141
0.12 release is near so I will look at it when making 0.12
