I'm all for an early merge but I think there has to be enough of the 
architectural changes in place to allow other people to understand the 
long term direction and also contribute.

I think the following are required for merge:

1) introduction of a new machine init function that returns a tree
2) code outside of dt.c, when -drive if=ide is specified, walks the tree 
looking for a node with an IDE decoration.  Finds the appropriate 
master/slave primary/secondary slot, and hooks up the BlockDriverState 
to the IDE device.
3) reading the machine description from a file

Basically, enough of the architecture that it's clear that we just need 
to do #2 for all of the remaining devices.  I don't think your that far 
from this today.

I'll respond in a separate note but the style is still off.
