Hey, my only suggestion for the mounting issue would be to use Samba.
As to the Zaurus SL-5500 ROM 3.10 synchronization problem I would suggest you check out my project ZSREP (Zaurus Synchronization Reverse Engineering Project). The url is http://zsrep.sourceforge.net
. It is a project that is working, and very very very close to solving this problem. There is nothing that synchronizes the Stock PIM apps on the Zaurus SL-5500 3.10 ROM and up with linux as of this point, not even Kitchensync. Hence, why my project exists.
We could use all the testers we can get for ZSREP if you decide that you are interested. I currently have code that can dump the contents of the Zaurus PIM data via the synchronization protocol. I also have code that has "Normal Two-Way" synchronization working (This is the synchronization that happends if you have already synced successfully with Windows Qtopia Desktop before. It only syncs the changes.). I am currently working an code that will do "Full Two-Way" synchronization (This is done when you have never synced before, or the sync info on the Zaurus has been cleared, etc.). Once, this is done and the proof of concept code is working. We will start developing a plugin for the chosen PIM. At this point it is looking like it will be fore Kitchensync and some others as well because some people don't like KDE.
