Fedora website. I *did* modify it a tad because I actually use ftdump to 
verify the content of the device trees I'm booting :)

However if anyone ever did want it, and you put it in your RPM, you'd 
need to change the name. Sorry I wasn't so clear, but I think it would 
be "good behaviour" if U-Boot or DTC or any other app (I can probably 
come up with some decent examples) did not use rather generic tool names 
which walk all over other tool names potentially on a system :)

That would be nice but it would never help me. I have to run the SUSE 
kernel of the last release, which right now is 2.6.27.7 - any efforts to 
get it in that have happened in the previous 6 months would have been 
missed by the time SUSE standardized :(
