I can't at the moment get it to output via speakers (the audio path switch doesn't seem to work), but unlike the 'EM' fmradio, it hasn't required me to keep bluetooth on and running.
Reception for me is pretty junk anyway apart from some local stations (which are only playing songs in other languages than English so I can't really appreciate those
) so don't think I'll use this in a hurry myself unless I'm out and about perhaps.
Also I just managed to crash and reboot the Streak playing around with fm_hcitool
I thought I'd try going to Settings -> Sound and Display -> Media Volume to try altering the sound level of the radio whilst the radio was playing and it all just froze at that point. Woops!
