kernel 2.4.27 doesn't set dma

[Alexei Chetroi <debian@lexa.uniflux-line.net>]

  Hi,

  I've recently upgraded to kernel 2.4.27 and noticed that my disk
doesn't use dma, though it was instructed to do so by hdparm. cat
/proc/pci shows me
  Bus  0, device  31, function  1:
      IDE interface: Intel Corp. 82801BA IDE U100 (rev 18).
      I/O at 0xfc00 [0xfc0f].
and on previous versions I've used module piix.o for this chipset. But
on 2.4.27 piix gets loaded but is unused, which is strange.
/proc/ide/piix isn't created either on module load with 2.4.27. Does
anybody had same problems? Any hints?

  Thanks in advance
