Hi,
I made a short Opie-SH script that allows you to switch between the USB storage class and network class gadgets for your Zaurus (2.6 kernels only). Additionally it allows the selection of the backing device (CF or MMC/SD) for usb-storage. Attached to this post is the script (copy to /opt/QtPalmtop/bin and make executable) and a .desktop file (goes in /opt/QtPalmtop/apps/Opie-SH). The icon might not be on your system but you can adjust as necessary.
It has been tested on an SL-5600 with OpenZaurus/OPIE 3.5.4.2-rc2. Hope it is useful for you.
Andrew
