Another way of achieving this is:
1) Install the osso-statusbar-cpu plugin.
[you will already have it under 'installable' applications in the application manager if you installed XTerm from maemo-hackers]
2) add a 'new' command:
Similar to last screenshot in above url: on statusbar click on newly installed 'clock-osso-statusbar-cpu' plugin / Settings / Commands / New and enter:
Description: fmradio
Command: fmradio

To open fmradio just click on the new command in the drop-down list.
You can also easily run other programs this way.

PS
i. above probably needs prior installation of the fmradio applet.
ii. I miss having access to the station drop-down running fmradio this way.
iii. ALWAYS check the audio level on the 'Sound' plugin on the STATUS bar, especially after switching between headset and loudspeaker output; unfortunately fmradio without fail reduces the volume
