That was considered at the time but we found that any combination of mirroring using the motherboard-based controller and the plugged in one wasn't stable (unbootable or soon locked-up) - the only way we could get mirroring to work was if both drives were on the 8212-based controller.
In reading Cox's notes on the 8212 awhile back, I distinctly remember that he did not have a lot of faith in using the 8212 as a "dumb" ATA controller with 2 channels. It's clearly rigged in hardware to always be used as a hardware stripe/mirror logic.
