In the meantime you can give it a go yourself - the code in question is a script not a binary, so you do not need a dev environment or to recompile to tinker! The main detection script is /usr/pluto/bin/StorageDevices_Radar.sh
In there you will find a function called Detect. In the first few lines you will see it 1) enumerating all the visible partitions using "cat /proc/partitions" but filtering out only those that start "sd" or "hd" using an awk command. It then moves on and eliminates any partitions starting with "sd" and "hd" already mounted, swap partitions, software RAIDS, etc. Finally, if there are any partions left, it will fire the DCE message that tells LMCE to add that partition. So in the first instance, you need to modify the detection script so that it also detects your partition type. This could be as simple as changing:
(sd|hd).[0-9] ... to
(sd|hd|<blah>).[0-9] ... in both locations in that script
Where <blah> will match the unique pattern of your RAID partition name when you type cat /proc/partitions
There could be more to it, as I haven't looked into much of the rest of it, but this change alone will at least add your partitions to the detected list.
