Just wanted to say that I'm having the same problem (and same
questions): I was able to upload 258076672 bytes (=246 Mb), but then
dfu-util dies with "dfu_upload error -16", and the FreeRunner reboots.
This is on Mac OS X.

At least one other person (you?) has indicated a similar problem at
http://wiki.openmoko.org/wiki/Pre-Flash_Backup.  Any ideas, anyone?
