Do you a a SCSI harddisk attached? Because you get sd_mod to load up which is for the SCSI disk but you don't get sr_mod which is for the CD. Is this an external CD drive? Post the contents of /proc/scsi/ dir to see what the kernel thinks about your CD. You see the new kernels have native ATAPI support for CD drives and this is compiled into the kernel but for external usb devices I think SCSI takes precedence. So your problem might be there. Unfortunately I don't have played around with USB CD drives so there isn't much I can do. I am pretty possitive though that if you google for it on the net you will definitely come up with something. The only thing that comes up in mind is force SCSI on the hdc by appending to the command line of the kernel that you boot the command: hdc=ide-scsi Maybe that wil help?
