atacontrol mode D PIO4 persist across reboots

[Philip M. Gollucci]

/var/run/dmesg.boot
ad2: 28667MB <SAMSUNG SV3002H PV100-11> at ata1-master UDMA33
ad2: FAILURE - READ_DMA timed out LBA=58711965
ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=0
ad2: FAILURE - READ_DMA timed out LBA=58711951
ad2: TIMEOUT - READ_DMA retrying (0 retries left) LBA=0
ad2: FAILURE - READ_DMA timed out LBA=58711964
ad2: FAILURE - READ_DMA timed out LBA=0
....
10-30 minutes later, it finally gets through the boot.

/etc/fstab:
/dev/ad2s1 /X ufs rw 2 2

the problem here is the device needs to be PIO4

$ atacontrol mode ad2 PIO4
current mode = PIO4

My problem is how do I get this to persist across reboot ?
