Yup, thanks to Matan Ziv-Av who did a few improvements and fixes and uploaded him-arabic to maemo extras.
The good part is the addition of the Hebrew keymap (And a few other things).
The bad part is dropping the dependency on ttf-arabic.
I need to create a metapackage called "arabic" that will pull all the packages needed to support Arabic.
Well, I'm still using the ttf-arabic packagess I created for Chinook (Available from my FTP as I don't have a Diablo repository).
I won't create the arabic metapackage anytime ssoon as I'll be on vacation. Wish me luck ;-)
