First, thanks to those who replied (and to any who did that I've
not listed):

Most everyone pointed me to the '-H' option in Solaris SVR4
cpio. (Simply using '-c' isn't enough.) Syd provided a
man page excerpt (which is not in my on-disk Solaris man pages):
An archive created with the -c option on a System V Release
4.0 system cannot be read on System V Release 3.2 systems,
or earlier. Use the -H odc option, which is equivalent to
the header created by the -c option in earlier System V
Releases, if the cpio image will be read by a pre-System V
Release 4.0 version of cpio.
John added that the next release of GNU cpio would be able to
read SVR4 cpio archives.
