I didn't try -c, but hdparm -d /dev/hda throws an error indication that 
the ioctl is not implemented.

neither DMA or 32 bit transfers appear to be enabled when hdparm queries.

I can't get to the machine untill tomorrow, so all this is prob memory, 
still i know for a fact that it will not let DMA get enabled.
