That didn't work for me.  On my machine  my cdrom drive  is only
recognized after I add  "ide-cd" to my /etc/modules.  But it seems
/etc/hdparm.conf  is processed before /etc/modules file during the
bototing sequence.  So in my case adding these lines to hdparm.conf
generates an error during boot that /dev/hdc is an unknown device, but
by the time the boot is complete, hdc is now defined, but dma is still
off. (and then I can manually run a hdparm command to turn it on).

I think I'll have to add a "sudo hdparm -d1 /dev/hdc" in some sort of
rc.local script (or the Ubuntu equivalent).  Something I haven't done
since my days on AIX boxes years ago... time to hit the man page to
learn how to do that on Ubuntu :)
