Hi,
I noticed that on the latest i386 snapshot (may, 17th),
there is no IDE (ATA133) DMA for the nForce4 chipset.
I took a look at the NetBSD driver (sys/dev/pci/viaide.c) : same
code for nforce3 and nforce4.
So I -successfully- tried the basic patch below.
I had expected speed improvements (33 -> 133 time ratio).
I won't be able to try soon an amd64 snapshot :-(
dmesg follows.
