Thanks for doing that, minor rewrite on this one:

+ <dd>On PowerPC guests, devices are assigned on the SPAPR-VIO
+ bus, which is a flat 64-bit address space, where each address
+ should be aligned on a multiple of 0x1000. Each address has
+ the following additional attribute: <code>reg</code> (the hex
+ value address of the starting
+ register).
I would say something like:
On PowerPC pseries guests, devices can be assigned to the SPAPR VIO bus.
It has a flat 64-bit address space, by convention devices are generally
located at a multiple of 0x1000, but other addresses are legal and
accepted by libvirt. A device can be given an address by specifying the
<code>reg</code> attribute, this gives the 64-bit address of the device.
If no <code>reg</code> value is specified libvirt will attempt to assign
a value for you.
cheers
