IDE subsystem has been deprecated since 2009 and the majority (if not all) of Linux distributions have switched to use libata for ATA support exclusively.
The replacement driver (pata_pdc202xx_old) has been available since 2006 and it supports all the hardware supported by the old pdc202xx_old host driver. Remove the deprecated pdc202xx_old host driver.
