For anyone who wonders what my "Argh" was about - basically there are two 'droid phones in the house - one 1.6 (X10 Mini Pro) and one 2.1 (Hero). I could not get the Hero on my WLAN (WPA2-EAP/TLS) using the same wpa_supplicant.conf as I had built on the X10....but after changing "eapol_version=1" to "eapol_version=2", it's working now.
Anyone wanting a hand getting client/CA certs working, I have it running

Also (and it's covered elsewhere now as well) - manually fiddling the wpa_supplicant.conf may break the chown/chgrp perms.
If in doubt, copy what you have, DELETE the file, and restart wifi.
This will recreate a base wpa_supplicant.conf
From a shell, run ls -la and note the owner/group uids/names (Hero 2.1 shows ids, not users). Then copy your file back and chown/chgrp the file and permissions as per the base template.
On my version of Hero, the user/group id needs to be 1010 and u+g need to be set to rw
