SATA 150

I have a Serial ATA controller on my motherboard.  I attached a Serial 
ATA 150 drive to it, and in dmesg I get:

ad4: DMA limited to UDMA33, non-ATA66 cable or device

Does this mean that the drive is only operating at 33Mhz, or is this 
just some way for FreeBSD-4.9-Stable to say it doesn't know any better?

(The drive works just fine.)
