Dennis,
you have a VIA kt8235 Southbrigde? You need kernel >= 2.4.20-rc2, to get UDMA working with that chipset. Of course, as Tomas pointed out, latest ac has much more ide improvements, so it probably would do even better with kt8235.
But >= 2.4.20-rc2 works like a charm here for me with the via kt8235.
