I'm assuming you are talking about the delivery option 3 described in
RFC 4284 appendix. Only the option 1 (EAP-Request/Identity from the
AP/Authenticator) was previously supported, so you would have needed to
configure this in the AP. Anyway, I added support for option 3 into
hostapd now, so you should be able to do this with the current 0.6.x
snapshot version from the git tree.

This is configured by adding a eap_user file entry that is pointing to
Identity method and configuring eap_message in hostapd.conf in the same
way as it is done for the AP/Authenticator delivery. Here's an example
eap_user file I used when testing this:

"user at example.com"	MD5	"password"
*	Identity
