Yes, for this -specific- issue, it was HAL polling the DVD drive multiple 
times a second, this fixed that:

# hal-disable-polling --device /dev/sr0 
Following symlink from /dev/sr0 to /dev/scd0.
Polling for drive /dev/sr0 have been disabled. The fdi file written was
   /etc/hal/fdi/information/media-check-disable-storage_model_DVD_RW_ND_3520A.fdi
