it looks nice, but now i'm confused.  how come i get this:

pciide0 at pci0 dev 5 function 1: Intel 82371AB IDE controller (PIIX4) (rev. 0x01)
pciide0: bus-master DMA support present
pciide0: primary channel wired to compatibility mode
wd0 at pciide0 channel 0 drive 0: <IBM-DARA-212000>
wd0: drive supports 16-sector pio transfers, lba addressing
wd0: 11513 MB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 23579136 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 4 (Ultra/66)

this is ultra 66.

pciide0: primary channel interrupting at irq 14
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33) (using DMA data transfers)

but now ultra 33?
