+// 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
