The last time I looked at the driver (I was one of the authors) most of
the SCSI compatible audio ioctls were implemented, as far as they were
possible (e.g. the Mitsumi does not support controlling the volume,
there is only on/off). I recommended compiling boot kernels with
the MCDMINI option, which excludes the whole audio stuff and makes
a driver that is only half the size of the complete one. You might check
whether this is the case for your kernel and might recompile one
without this option if it was set.
The eject ioctl sends a special command to the drive that is ignored
by Mitsumi drives that do not have this feature (it should work on the
recent FX001D and FX001DE, but I couldn't verify this yet).

Besides the problem that xcdplayer had to be persuaded to use the right
device name and the SCSI ioctl set, this worked with the mcd driver some
time ago, but I do not guarantee for any "improvements" that have been
introduced since the original version (see also the probing problem).
