False: 2.6.0 - 2.6.19: libata guarantees that all PCI BARs are reserved to the libata driver. 2.6.20: no guarantee that all PCI BARs are reserved to libata driver. Real-life ata_piix example already provided, where a PCI BAR is no longer reserved to the driver. 2.6.21 - infinity: libata guarantees that all PCI BARs are reserved to the driver.
