from drivers/ide/ide-features.c:

/*
 *  All hosts that use the 80c ribbon mus use!
 */
byte eighty_ninty_three (ide_drive_t *drive)
{
        return ((byte) ((HWIF(drive)->udma_four) &&
#ifndef CONFIG_IDEDMA_IVB
                        (drive->id->hw_config & 0x4000) &&
#endif /* CONFIG_IDEDMA_IVB */
                        (drive->id->hw_config & 0x6000)) ? 1 : 0);
}

If i see well, then this is always same whether CONFIG_IDEDMA_IVB is
defined or not.
What's the clue?
