// The generic device simply hooks ranges of ports, addresses, and irqs
// if they are not already hooked
//
// for each hooked port, it simply executes reads and writes and the same physical port,
// for each hooked memory range, it simply executes reads and writes on the same
//    physical memory addresses
// for each hooked irq, it simply injects the irq into the VM
//
// These operations are also logged to serial (optionaly)
//
// If you attach a generic device *last*, you can capture all ops that are not
// already hooked, and capture a log of VM activity with respect to them.
//
// The effects of using the generic device should be identical to 
// doing passthrough I/O, but with logging, and, of course, slower
//
