I've got exactly the same problem as the starters-post at my university (University of Twente, Netherlands). As far as I know we also use the Eduroam project.

Whatever I configure in Maemo under 'Connections', the 'Connection name' never replaces the ESSID-name when I look for available Internet connections from the homescreen.

So in my case: I have made a connection named 'UT WLAN', that uses the ESSID "WLAN" of my university. I followed the instructions in the above mentioned wiki page. But when I search for available Internet connections, only "WLAN" is showed en when I click that, the N900 asks for a WEP-key.

I searched the internet for this problem, but could not find anything except this thread. What can be the problem?
