What south bridge do you use? Some of the newer ones offer 32bit
addressing capability for DMA.

Via686a. As I understand it, 32-bit DMA uses the DMA_HI_PAGE_x registers
from 0x487 to 0x48a, and the Via manual doesn't claim to have any
registers in that range. The only 32-bit DMA southbridge I've
encountered is the Winbond chip on the Sandpoint, and that chip doesn't
have UDMA66, USB, and audio.

And the Winbond South Bridge on the LongTrail (most probably the same chip).
