6   Configure up a Z8530/Z85C30 or Z85230 chip. We check the device
7   is present, identify the type and then program it to hopefully
8   keep quite and behave. This matters a lot, a Z8530 in the wrong
9   state will sometimes get into stupid modes generating 10Khz
10   interrupt streams and the like.
11   </p><p>
12
13   We set the interrupt handler up to discard any events, in case
14   we get them during reset or setp.
15   </p><p>
16
17   Return 0 for success, or a negative value indicating the problem
18   in errno form.
