Sharp Zaurus 5500 with Suse 9.2

I followed the instructions at http://portal.suse.com/sdb/en/2004/12/jk_zaurus_usb.html But I cannot get the Zaurus to sync with Qtopia. I have it to where I can ping it from my PC, but thats it. Anybody have this working? Also, I am using the Sharp ROM Version 2.38. I am not opposed to trying OPIE or some other open ROM, but then, how would I upgrade or change the ROM if I cannot sync with the Zaurus?
