Looking at the CVS log and diffs, there were quite a number of changes
since 2.0.5-RELEASE, some of which have to do with tracking the drive status.

A behavioral change I noticed "recently" is that I have observed the
drive to no longer eject in response to the button when the disk is
mounted.

My suspicion is that there has always been some sort of race condition,
perhaps even in the hardware, that causes the Mitsumi sometimes not to
know there is a CD in the drive.  Cycling the door used to change its mind,
but perhaps more recent changes to the driver have now blocked this type of
workaround.

I can't say too much more that isn't basically wild speculation.
