Yep, wd0 is a disk managed by the wdc0 controller.

Probably wd2 on wdc1.

Hmmm. What you really need to do is boot up the old drive and look at
its fstab. Oh, and write them down! ;-)

Each partition in there can be translated for the mount command as

	When used to boot:	When mounting:
	wd0sXY			wd2sXY

So if indeed you find that your root partition on the old drive's fstab
is given as wd2s2a (I'd have expected wd2s1a), then the mount command
required once you've booted off the new drive is:

	mount -r /dev/wd2s2a

Ha! :-)

	cd /dev
	./MAKEDEV wd2

Anyone who can't understand what that's like probably isn't worth
listening to in any case. ;-)

Have fun!
