Ron and I just dicurssed about the enable/disable mechanism for
amd8111. We are going to implement a slightly better one soon.

Actually, the enable/disable for devices in amd8111 is multiplexed
in amd8111_enable and the device_operation::enable() is directed to
amd8111_enable. We are going to demultiplex this and each devices
has its own "real" enable method.
