Yes.  Thanks for the confirmation.

0x0ff0 LIMITS all wd* interfaces to no dma, in my case PIO-4, 
so you wind up chugging down ALL wd* disks (from my dmesg):

wd0 at pciide0 channel 0 drive 0: <WDC AC28400R>
wd0: 16-sector PIO, LBA, 8063MB, 16514064 sectors
wd0(pciide0:0:0): using PIO mode 4
wd1 at pciide0 channel 1 drive 1: <ELITE PRO CF CARD 16GB>
wd1: 1-sector PIO, LBA, 15280MB, 31293440 sectors
wd1(pciide0:1:1): using PIO mode 4
ppb1 at pci0 dev 1 function 0 "Sun Simba PCI-PCI" rev 0x13

So I'm now wondering whether we can turn these flags on on a
disk/channel basis.  I'd assume that the reference "channel"
implies that there is some possibility of this?
