Can this be the time when we added proper support for IDE M/DMA mode ?
Previously, our driver could do DMA, but couldn't configure the disk DMA
mode, leaving it in whatever state the firmware/MacOS set it up. Around
2.2.x (early, I don't remember when exactly), we added some code to
configure the timings properly.
Ben.
