Anybody wanna give this a quick test? It doesn't actually _do_ anything
yet, except attempt to detect the PATA port.
Latest libata...

The latter 2.6 patch applies to the current BK tree, will be -bk6 when
that snapshot is generated tonight. It _should_ apply to earlier
2.6.5-rc2, but applying to earlier kernels you -may- need to
s/pci_dma_mapping_error/pci_dma_error/, or completely remove the
pci_dma_[mapping_]error() check.

Thanks for testing.
Is your PCI id listed in this function?
static int pdc_pata_possible(struct pci_dev *pdev)
{
if (pdev->device == 0x3375)
return 1;
return 0;
}
If yes, hrm. :)
If no, just unconditionally return 1 there and see if you get the
message in pdc_host_init():
/* check for PATA port on PDC20375 */
if (pdc_pata_possible(pdev)) {
tmp = readl(mmio + PDC_PCI_CTL);
if (tmp & PDC_HAS_PATA)
printk(KERN_INFO DRV_NAME "(%s): sorry, PATA
port not supported yet\n",
pci_name(pdev));
}
