Is there a dfu-util that can successfully backup an existing flash?

[Peter Rasmussen]

This sounds great, and I have some questions regarding it.

I have a GTA01bv4 and wonder if it will be working on that one as well?

Which leads me to what I am always worried about when updating uBoot: 
How do I know it won't brick my Neo?
I only have the basic version with no debug card, and I don't know any 
in the neighborhood with one, so I haven't updated my uBoot for quite 
some time (Now it is: July 5. 2008).

Except for the mentioned fix, how do I know about potential important 
fixes to uBoot?

Thanks,
Peter
