So, you're saying that I can't boot from an ATA drive on a PCI-based
controller card?  What is the background for this limitation?

Also, I'm curious about the effects of turning off hw.ata.ata_dma;
outside of using some CPU time, what are the likely effects of this.
For instance, is this likely to slow down disk transfers, assuming
that the system is mostly idle?
