You probably need DMA access on your HD to get enough read speed to read the disk. I have used 2.2 kernels on a via 686 south bridge and gotten about 3MB/sec, and after switching to a 2.4 kernel with support for that chipset, dma was enabled and I got 27MB/sec which would help a lot for doing fast writes, and also makes the system much much faster. Check /proc/ide/hda/settings, and make sure dma is currently on, and make sure the kernel is new enough to support your chipset fully.
