With recent ide patches, the ide driver seems to try to use DMA mode even for a drive which dosen't support it. CONFIG_IDEDMA_PCI_AUTO is enabled but even so with the stock kernel this dosen't happen. older patches didn't have this behavior either. Is this change intentional ?

This may not be a major problem, as nobody probably uses such an obsolete drive nowadays. The following patches have been tried:
ide.2.2.18-22.all.20001120 ide.2.4.0-t11.1120.patch
