The tech docs at http://www.qemu.org/user-doc.html could really use some more 
information on this area.

The "hw" directory contains both definitions of individual pieces of hardware 
(such as i8259.or ide.c) and motherboards that integrate lots of pieces of 
hardware together (pc.c or integratorcp.c).  They're treated as 
interchangeable, both of them are initialized with a function ending 
in "_init", and there's no easy way to distinguish between them except by 
inspection.  (I could easily be wrong about this, but if so I haven't found 
the pattern or documentation yet.)
