There's no way to reliably know if a PCI064x controller is enabled or not.
If the driver finds a PCI064x, it will assume it is enabled unless the

This will be a problem only if the controller has been disabled in the BIOS
and another controller has been installed and uses the ISA legaty I/O ports
and interrupts.
