The 'cdrom' module is not a driver but is *used* by drivers. The driver
for the SATA interface (ata_piix in this case) is supposed to detect
SATA devices and request the appropriate driver for the device types
found (sr_mod for a CD-ROM). Since sr_mod has not been loaded, it
appears that the problem is in device detection. (And loading sr_mod
should have no more effect than loading cdrom, because no device has
been found for it to bind to.)
