so I simply added root=sd0a to /boot/boot.ini's boot line. That resulted in:

Should this have worked?
Can you post a full dmesg?
As Michael says the usb explore code doesn't wait properly here. There
was code, but it's bit rotted.
Tried a similar configuration on the Pi (i.e., same physical disk, but
did add ta powered USB hub), and it's working fine. Hmm, perhaps it
is a power issue.
However, I get the feeling that there's more going on. For instance,
just adding an entry to /etc/fstab to mount of /dev/sd0a on /mnt fails
during boot (fsck can't access /dev/rsd0a during the boot). Yet once
the system is booted it works fine.
The USB disk is probably starting too slowly to be recognized at this
point. There needs to be some kind of spin-up delay in the kernel to
handle this situation.
There used to be one as mentioned above.
Can you try -current as of today - I made a change to dwctwo(4) this
morning that *might* help here.
