You can use hdparm on the hard drive block device to tell if DMA is
enabled:

plhofmei at Oneill:~$ sudo hdparm /dev/hda
Enter password for SUDO:

/dev/hda:
 multcount    = 16 (on)
 I/O support  =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 nowerr       =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 9729/255/63, sectors = 156301488, start = 0
 busstate     =  1 (on)
