Ok well if you are sure about this then at least we know it is not a
hardware (jumpers, cable, connectors) problem.
With my WD IDE drive:
bob@trantor:~$ dmesg | grep -i dma
DMA 0 -> 4096
DMA zone: 32 pages used for memmap
DMA zone: 0 pages reserved
DMA zone: 4064 pages, LIFO batch:0
atp870u: use 32bit DMA mask.
NFORCE2: 0000:00:09.0 (rev a2) UDMA133 controller
ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA
ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA
hda: UDMA/100 mode selected
hdc: UDMA/66 mode selected
hdd: UDMA/66 mode selected
parport0: PC-style at 0x378 (0x778), irq 7, dma 3
[PCSPP,TRISTATE,COMPAT,EPP,ECP,DMA]
bob@trantor:~$ readlink /sys/block/hda/device/driver
../../../../../bus/ide/drivers/ide-disk
bob@trantor:~$ lsmod | grep ^ide
ide_cd 36224 0
ide_disk 15648 8
ide_core 108292 4 ide_cd,ide_disk,amd74xx,generic
Not sure if any of that is of help, but perhaps you could show us the
output of dmesg | grep -i dma
