I had quite a lot of trouble with this one as well, when I first tried
the 2.6. kernel; my experience was similar to the OP's. When things
didn't work I also went back to scsi emulation but I had no luck with
that either. The solution, eventually, was to make a link:
/dev/cdrw > /dev/hdd
(I have two cd drives; if you have only one I suppose it would be
/dev/hdc.)
Incidentally, cdroast doesn't seem to like this arrangement so you have
to use cdrecord with the 2.6 kernels as far as I can see, but I've
decided this is an advantage anyway.
