We've been discussing having a command that's something like 
'info-device ioapic' that would dump the device state based on what's 
stored in VMState for the device.

The advantage of a command like this is that it works for any qdev 
device making it much more useful.

The disadvantage is that at the moment, we store ioredtbl as an array of 
uint64s.  To get the level of info you're looking for we would need to 
teach VMState how to decode this structure.
