using_dma was off

after turning it on (/dev/cdrom points to /dev/hda for me) :

hdparm /dev/hda

/dev/hda:
  IO_support   =  0 (default 16-bit)
  unmaskirq    =  0 (off)
  using_dma    =  1 (on)
  keepsettings =  0 (off)
  readonly     =  0 (off)
  readahead    = 256 (on)
  HDIO_GETGEO failed: Inappropriate ioctl for device

Nevertheless, I then insert a CD and play it, and the CD-pausing problem 
is still there.  Perhaps modify readahead?

How does it "default on" - do "recent snapshots" have to turn it on in 
bootscripts for all applicable drives? or just /dev/cdrom? or something 
else?
