Ah ha! I was afraid there might be a reason other than a simple
omission of the necessary hooks as to why some interfaces like bge(4)
were not used as entropy sources. I was hoping it was just because
of (minor) performance issues, but this sounds a little more severe.
Is there any simple flag that can be checked to see if interrupts are
currently polled or not?
