The latest version of ide-cd.c has a special case for the NEC 260 drive and
doesn't attempt to query its capabilities. Unfortunately, it doesn't actually
set the known capabilities of the driver either.

To reenable the support for audio and eject on this drive, I need the following
patch (against 2.2.13):
