No - it's picking the correct driver - but if I force it to use the
wrong driver - scsi2_cd - which is a generic driver that can only
read the drive - reading the table of contents (TOC) works fine.

If I let it use the correct driver, it locks up when reading the TOC,

Yep - I did that - but I have stepped back from the issue of actually
writing to the disk since it can't even read the TOC.  It's a lot easier
to show that it's the driver that's at fault because I can compare the
behavior of scsi2_cd with cdd522 (which is the auto-detected driver),
all other things being equal.

Well, I guess I give up on this one - I'll go and buy an new CD writer
and chalk up the $15 to experience.  It's not worth the hassle to fight
it.
