Thanks, Frank, but the nad2nad still won't work for me. This is what *did* work, though:

[root at nonesuch nad]# cs2cs +proj=utm +zone=10 +datum=NAD83 +to +proj=utm +zone=10 +datum=NAD27 -r <<EOF

502665.79	5944824.42 0.000

Looks like it wants Easting first :-))  I'll keep plugging away at the mysteries of nad2nad.
