Scroll lok and page up work, and what I see is the following, copied by hand:

    atapci0: <Intel ICH8M SATA300 controller> port
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x1c30-0x1c3f,0x1c20,0x1x2f at
decive 31.2 on pci0
    ata0: <ATA channel 0> on atapci0
    ata0: [ITHREAD]
    ata1: <ATA channel 1> on atapci0
    ata1: [ITHREAD]

Then, at the end, I show:

    Trying to mount root from ufs:/dev/ad0s2a
    ROOT MOUNT ERROR:
    If you have invalid mount options, reboot, and first thre the
following from the loader prompt:

etc.

OK - when I get home from work, I'll download and see what that does for me.
