Thanks. 

QUESTION: how do I test these devices (cdrw and dvdr drives) to ensure
DMA is still enabled? I cannot figure out yet what parameters to give
hdparm -I /dev/WHAT?

Wizard root # hdparm -I /dev/cdroms/cdrom0 
/dev/cdroms/cdrom0 not supported by hdparm
Wizard root # 

When SCSI emulation is not turned on I can do hdparm -I /dev/hdc, but
with SCSI emulation enabled hdc and hdd don't exist.
