Libata pata_legacy handles this itself for all known cases using the ruleset
IF any PCI device -> no PATA legacy scans beyond IDE0/IDE1 IF any PCI IDE in legacy compat mode -> No pata_legacy bind to that port IF CS55x0 or MPIIX -> read the chipset magic [these are the obscure 'not PCI but not ISA' specials]
