What's happened to CDIOCREADAUDIO & friends?

Hello,
We used to have this ioctl in old ATA/ATAPI driver (and still do in
sys/cdio.h); apparently, it's no longer there with ATAng. Is this a bug or
feature? And if this was planned what's going to replace it? As it is,
this change has broken cdparanoia cooked ioctls interface (BTW, that's why
it doesn't work without root privileges), xmms and xine CDDA support and
perhaps several more ports. Oh, incidentaly, cdparanoia (at least) is
broken under -CURRENT in yet another way: it still looks for
/dev/{acd,cd,mcd}%c -
ports/audio/cdparanoia/files/patch-interface-scan_devices.c
- which aren't there after cloning removal).

Regards,
Vladimir
