Oddly, the command at least executes and doesn't MCE (but it's not at all happy either) if I use ATA_PROT_PIO. I wonder if ATA_PROT_NODATA is buggered on this sata_nv chip (Asus A8N-E). Weird...
Try turning off ADMA using the module parameter, and see if ATA_PROT_NODATA magically works.
ADMA is an advanced command execution mode, and it may not be appropriate for certain non-data commands.
