The following patch should be appropriate for your configuration.
Unfortunately, I have not access to ALi hardware at the moment - I cannot
test it.
Andre, is there any reason that all the PCI IDE drivers in 2.4 depend on
CONFIG_BLK_DEV_IDEDMA_PCI instead of CONFIG_BLK_DEV_IDEPCI ?
As you see, pure PIO configuration for PCI IDE is still useful for some
people...
