I've been having this same problem, but apparently my VIA version
doesn't match 82CXXX, so I'm completely dead in the water for DMA (I
know, VIA is bad). I want to buy a PCI IDE controller card that will
support DMA, will this solve my problem? If so, what kind should I get
so it will be Debian-compatible?

Any suggestions? If someone out there is using Debian and a PCI IDE
controller, I'd love to hear from you.
