I've found that the Feitian ePass2000's and the Yubico keys allow for importing of the private key. They do usually want the 'extra' flags to specify use:

	pkcs15-init --store-private-key .ssh/id_rsa-foo --auth-id 01 --key-usage sign,decrypt --label "ssh key of me at mydomain.com"

and some fail silently when you do not provide these.
