Slowly the necessary pieces come into focus:
1) Find the writable-or-not code of sr_mod.ko.
2) Find the writable-or-not code of ide-cd.ko.
3) Move (1) and (2) into cdrom.ko.
4) Teach cdrom.ko to fetch op x46 GPCMD_GET_CONFIGURATION header.
5) Teach cdrom.ko to fetch all reportedly available op x46 data.
6) Learn that more than DVD-RAM is writable.

All ok now.

Not yet complete.

Still feels kluged.
CD-RW and DVD+RW support random rewrites if load balanced. Those
designs have not pioneered a standard way of saying truly random
rewrites supported, other than saying DVD-RAM.
