Here's what I got after setting up the drives as
ccdconfig ccd0 0 0 /dev/wd1e /dev/wd2e

I even tried to label them assuming that the d: partition reflected
reality, but got:

ROOT> disklabel -rw ccd0 ccdcfs420x2
disklabel: partition a: partition extends past end of unit
disklabel: partition c: partition extends past end of unit
disklabel: partition d: partition extends past end of unit

Here's the disklabel I tried:

ccdcfs420x2|@ CFS420's setup as a ccd:\
        :dt=ccd:ty=ccd:se#512:nt#1:ns#2048:nc#812:\
        :pa#1663200:oa#0:ta=4.2bsd:ba#8192:fa#1024:\
        :pc#1663200:oc#0:\
        :pd#1663200:od#0:

The partition size number does reflect the underlying labels; wd1e and
wd2e each have parition sizes of 831600.

The number of sectors and tracks I find weird, though...

Any clues?
