Oh my gosh... solved the f**cking problem

You need "mtd-utils" in meego - that's the problem. So you actually "just" need to get "mtd-utils" and "mtd-utils-ubi".
Then you've got "ubiattach" and everything works like a charm with Hurrians commands.

Thank god!

I'm gonna write a more complete version of what I did later...
