Ok, do the bootup messages say anything support for that chipset? On my PIIX4 the kernel detects it and enables the maximum ultradma completely automatically. Check the VIA chipset support. Does it specifically mention this chipset? Lastly, have you tried Andres big-ide patch, which twiddles support for several chipsets not in the main kernel.
