Umm, who is 'they' and where do they 'make a big deal'?  I've not seen it
anywhere, and can attest that I've never paid the slightest attention to
what version of dfu-util I've used.  I've flashed my FR at least 16 times,
several different distros, no problems with dfu-util or the flashing
process.

That's a different matter - 'upload' (reading the flash memory and creating
a jffs image on the host of the rootfs) is still broken in
dfu-util.(http://docs.openmoko.org/trac/ticket/676) 
http://wiki.openmoko.org/wiki/Pre-Flash_Backup covers using dfu-util or
other approaches to backup the current flash, (and warns that upload is
broken) and http://wiki.openmoko.org/wiki/NeoTool covers NeoTool - a handy
GUI that runs the console-only dfu-util for you.  NeoTool also supports the
tar-based backup, which is known to work reliably.
