According to the _Apple IIgs Firmware Reference_ (Apple's book - published
jointly by Apple and Addison-Wesley), the Smartport firmware sets a flag
when a disk is ejcted from a A3.5, Unidisk 3.5, or any other Smartport device
that reports this event back to the Smartport driver.

In theory, the OS checks ALL of the device status flags - If GS System 5 is
getting confused, that would mean some one forgot to do the status checks.

BTW: SCSI interfaces are also supposed to provide these same flags - but
as of rev C, Apple's SCSI card doesn't set the disk-ejected flag.
