Looking at the dmesg(1) from the last boot,

Makes me think the system is not recognizing the device as CDRW,
only CDROM.

You're right, and that's the key point to start from.
Don't worry about ATAPI/CAM; it won't be used by burncd, and won't
work any better than direct ATAPI drivers if the device isn't
recognized as a CDRW.

The funny thing is (unless I recall incorrectly, which is possible
before my first cup of coffee for the day), the ID string is provided
by the device itself. And I just looked it up; CRD-8400B is
definitely a CDROM. So I don't think the OS is confused; if anything,
the device itself is what's confused.

Just to doublecheck: are you really sure you haven't changed the drive
since the last time you burned a CD?

Nope, haven't changed the drive. Went and had a look at the front and
it's got "CD/RW" on the "disc" symbol on the front of the tray. But
going back to some old dmesg(1) from this same box when the buring
worked back in 4.x,

Hmmmm...
