Hmm. with revision 1.22 of ata-lowlevel.c, the system boots with the
atapicam device, and writing DVD+R media with growisofs seems to
_almost_ work. Unfortunately, almost isn't worth much in these kind of
things.

growisofs -Z /dev/cd0=premastered.iso 

gets to the end of writing and prints 

/dev/pass0: flushing cache
/dev/pass0: closing track
- [unable to TEST UNIT READY]: Input/output error

the resulting coaster won't mount 

convex# mount /dev/cd0 /mnt
mount: /dev/cd0: Input/output error
