You said that they are IDE drives on older 500 MHz system, so hdparm should be right application. I'm not familiar with hdparm internals so I ran test on my older computer with 10.3 alpha 1 and it shows the same error, although I used symlink hda that points to sda ie. solving naming: hdparm -c1 /dev/hda That might be because the device ID major is changed from 3 to 8. Which probably confuses hdparm. The hdparm -i /dev/hda claims that parameter is not applicable for the device. The same works fine in 10.2.
The cause is the transition to libata IDE drivers. Libata currently doesn't support DMA mode change. See https://bugzilla.novell.com/show_bug.cgi?id=264681#c14 for details.
