I figured out simple trick... I downloaded .install file to N800 and corrected it with text editor. It seems that currently repository for diablo is not present, so you just simply enter older repositories (don't remember exactly - I'm writting out of my memory)...
Check URLS in install file and set it accordingly. For me Orbiter seems to be working ok (beside few problems that I've already posted mantis thread and showed to NiteMan...).
The trick is that newest FW is looking for packages in ..../diablo/... directories, but most of repositories don't have that entries yet...
Yep thats basicall correct.
You can test our new Nokia Tablet repos here http://diapub.com/~michael/
Michael has done most of the work...thanks Michael :-)... and we provide the server and a little technical backup/help.
The Nokia Tablet repos is open for use by the community. There may still be some kinks in it though ;-)
All the best
