For the former issue I sent a patch "qdev: Add helpers for reading  
properties" yesterday:

http://patchwork.ozlabs.org/patch/99536/

That allows to access properties of arbitrary DeviceState by name,  
e.g., qdev_prop_get_uint32(dev, "irq").

It currently depends on the open question of how to model bool  
properties but I can reorder the two if needed.
