I was hoping that Nokia was sloppy and tried sending SIP INVITES with
PoC headers but the phone was ignoring them or answering with a
"unsupported media type" or similar.

Unfortunately, I also wasn't able to register the PoC application with
my asterisk.
Anybody knows if somebody works on an PoC / push to talk over cellular
implementation for *? I studied the 3GPP / Nokia drafts about 2 or 3
years ago. It doesn't look too complicated but I'm not exactly a gifted
programmer :).
