No.  I'm firmly in the DT-still-has-to-prove-itself camp and I wish I 
I'd never had to deal with it.  I believe that the current way for 
configuring hardware on ARM is more reliable and less prone to errors 
and bugs such as what you described about Freescale powerpc boards.  

And for the record I don't believe the current crisis about ARM board 
code duplication can be directly linked to the lack of DT support on ARM 
even if many people are blending those issues together.

If so then this whole DT idea has been oversold with false pretenses.  
In good faith I'm willing to try it out and so I'm working towards its 
implementation for ARM not against it, but if the DTS files are to be 
maintained out of tree then all I can see for the future is additional 
maintenance pain not less.
