Probably the latter.  Right now no kernel config files assign a drq to
wdc? because most IDE controllers (and drives) lack support for it.

You need to append 'drq X' to the wdc0 line in your kernel config.
Which DMA channel is used depends on your motherboard; you may be able
to extract the information from your machine's BIOS setup screen(s).
