You don't. Basically it is controller dependant. Pretty much all the newer controllers support the 32bit PIO data cycles. Most PCI controllers it makes no speed difference but host bus controllers (especially PIIX/ICH) really benefit.

Nearly all onboard "PCI" controllers (integrated into the host chipset) benefit hugely, but I suppose that is what was meant by "host bus controllers".
