Sadly,
Michael never got very far. So no, nothing to build on from him, I think. I'm probably the only one except for Hans Dorn who did any Linux stuff at all here at lunatics.at.
So - since you posted you'd like to get it fixed, depending on the level of support you get from us - let's give you support, then.
I can only speak for myself, but I personally would like to see a combination of our efforts. I've added you to the "Linux porting Team", which should give you a few extra powers here.
Regards,
Simon.
