There is a utility called "certpatch" developed by OpenBSD folks for including the SubjAltName extension. I have modified it a little bit to suit my need.
This utility modifies the certificate in place and regenerates the hash. Perhaps you can modify it a little to suit your need. If all you need it add an IP address, e-mail or FQDN SubjAltName extension then this utility may help. Do let me know if this is what you need and then I can mail the program that I have.
