No DMA?

This is on a Cyrix box. Full dmesg output below.
DMA works perfectly fine on this box, under Windows, FreeBSD 4.7,
5.0-RELEASE, but on 5.0-CURRENT it stops working.
I'm not entirely sure when it stops working, I merely cvsup'ed after
installing 5.0-RELEASE a few weeks ago, and it stopped working. I cvsup'ed,
made kernel and made world yesterday, and still no dma.
I am guessing it was turned off on this particular board/ata controller for
a reason.. And perhaps there is some way to override that and turn dma back
on anyway?
Thanks,
Martin.
