I have another machine that also has the IXP chipset and that machine has
also a SiS integrated RAID SATA controller, I run linux on that so
there is no problem.

But the machine I'm I setting up for NetBSD-2.0 is a barebone and the SATA
seems to be intergrated into the IXP chip, here is the output from pcictl:
000:20:1: ATI Technologies ATIIXP UltraATA/100 IDE Controller (IDE mass
storage, interface 0x8a).

Here is parts from the dmesg for the machine(with my new driver):
atiide0 at pci0 dev 20 function 1
atiide0: ATIIXP UltraATA/100 IDE Controller (rev. 0x00)
atiide0: ATI Technologies ATA100 controller
atiide0: bus-master DMA support present
atiide0: primary channel configured to compatibility mode
atiide0: primary channel interrupting at irq 14
atabus0 at atiide0 channel 0
atiide0: secondary channel configured to compatibility mode
atiide0: secondary channel interrupting at irq 15
atabus1 at atiide0 channel 1
wd0 at atabus0 drive 0: <IC35L120AVV207-0>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 115 GB, 239340 cyl, 16 head, 63 sec, 512 bytes/sect x 241254720 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
wd0(atiide0:0:0): using PIO mode 4, Ultra-DMA mode 5 (Ultra/100) (using
DMA data transfers)
wd1 at atabus1 drive 0: <Maxtor 6Y120M0>
wd1: drive supports 16-sector PIO transfers, LBA addressing
wd1: 114 GB, 238216 cyl, 16 head, 63 sec, 512 bytes/sect x 240121728 sectors
wd1: 32-bit data port
wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd1(atiide0:1:0): using PIO mode 4, Ultra-DMA mode 5 (Ultra/100) (using
DMA data transfers)


The wd1 is the SATA disk.
