Hi,
this other Hungarian localization was new for me also, as we came to the same conclusion with firstfan when we were talking about it. Seems like the guys didn't care about the copyright (which, in this case, is a benefit for all IMO). I think it's better this way (having one localization package for the OS and another one for the apps, easier to maintain), but correct me if i'm wrong. At least more Hungarians are involved with the N900, yay!
@Venemo: it's not better, it's different. One package is for the underlying OS, the other is for the applications.
