I have the same with kernels after 1.1.76. 1.1.76 itself still did
access the sg device of the CDROM properly with cdda2wav.
I really have no idea if this is related, but I thought I'd throw it
out in case it caused some sudden realizations or something. I am on
both the scsi list and the kernel release list, and got this from

If you have SCSI CD-ROMS, you might want to apply the following patch
from Linus which fixes a (very small) error in the kernel:
===== sr.c one-character patch: apply by hand =====
===== the "sg_template" should be a "sr_template" =====
