The support is included in 2.1.73 and above.

Yes, the ATAPI cdrom will also be mapped to /dev/sr0, and you would
be able to mount it using the SCSI cdrom driver.
Alternatively, in the 2.1.x kernels you can compile both the SCSI emulation
and the native ATAPI cdrom driver as modules, and switch between them using
"rmmod ide-scsi" and "insmod ide-cd". "cat/proc/ide/.../hdx/driver" will
display the current driver :-)

I think that the "blank" argument to cdrecord can be used to erase a CD-RW.
It would not work with the 2.0.x patch in README.ATAPI (the constant timeout
is too short), but is should be supported with 2.1.73 and above.
