Hehe... they changed the website one day after this thread started, so when deeteroderdas replied, Maemo was not listed.

Still, as far as I understand it, Maemo-devices are compatible with the service (you can connect to the Nokia Chat server), but they of course do not run the software needed for S60-phones. The word "compatibility" is misleading here.

Even more, I could connect to Nokia Chat from day 1 on my tablet because it's a simple Jabber-Server, nothing else. The new package seems to be more of a marketing thing (making users aware that there is a chat service running at ovi.com) than an application that really does anything.

Except, of course, I'm still missing the point and the proprietary parts Nokia chose to put on top of the XMPP-service (even though there's open standards to do the same) are somehow included in the Telepathy-configuration. Given there's no settings for this when you create the account, I doubt it, though.
