[Bug 110636] hdparm - cannot set dma on IDE hard drive that works via pata

Binary package hint: hdparm

In Feisty final, all of the disk drives are now called sdX instead of hdX. (as i understand they are now using the new pata driver. I have a regular IDE Drive and i want to enable DMA on it using the hdparm. Here is what i get:
# hdparm -v -d1 /dev/sda

/dev/sda:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Inappropriate ioctl for device
 IO_support   =  0 (default 16-bit)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 9729/255/63, sectors = 156301488, start = 0

What can be done to enable DMA?
