Sorry, I think I missed the beginning of this thread. 

The biggest problem is not getting acceptance for this, but getting the
work done. Adding OF support to x86 based Linux systems can either be
done as a hack, or by creating a clean abstraction level which can be
used (on all platforms?) to plug in a certain set of firmware support
functions. This means taring out PCBIOS and EFI and creating modules
from those, and then add an OF module. 

And then the good question is: Why should we?

 - Because ACPI is a crappy attempt of a device tree and the DSDT
   is fixed until someone hacks dynamic stuff in there. 

 - Because LinuxBIOS does not export the device tree in the LinuxBIOS
   table.

 - Because OF is the right thing to do. Of course. ;-)
   But unless we are looking to support STOP-A, we get 
   _most_ things done without any communication.

I suggest we talk about the second of those. Would that not be exactly
what we want?
