A quick test would be hdparm -tT /dev/hda
(or whatever drive you are concerned about.) Greater than 15MB/S is almost certainly DMA but good DMA from newer drives should be 25-50MB/S You can look at the drives parameters using hdparm and reading through the man page to understand what all the values mean.
