I've tried, and others have too, but that didn't seem to work. I don't remember the message exactly, something on the lines of "No supporting hardware found."
You definitely need to play around with the rom to get it to work. This is why the SpiritFM.apk is the easiest option... even the expired 'free' version with no RDS. How often do you look at your phone to see the song/artist info anyay?
