No, this data has to be coming from kernelspace, via the driver that is 
exporting its interface.  There are all sorts of attributes that other 
drivers can make available - like device serial numbers - that can ONLY 
come from the hardware itself.

I have a strong suspicion that setting up additional kobj structures 
(one per attribute) and associating them with the registered device node 
may be the key to this.  But I need to do some digging (or perhaps 
someone can figure it out and tell me about it)...
