 See http://lists.debian.org/debian-kernel/2004/08/msg01909.html
IMHO it also related to those bugs. As Frédéric BOITEUX says in his
message, diffing between 2.4.26 and 2.4.27 ide-probe.c gives this:

        ideprobe_done++;
        return 0;
 }

So Dear "Debian Kernel Team", is these changes only necesarry to make
DMA working again in 2.4.27 or there're some other things too? We do
want to upgrade to 2.4.27, but DMA disaster stops us.

  Thanks in advance.
