Unfortunately 3.103 (from the debian unstable repository) does not
appear to work at all for me.  If I set the frequency:

radio -f 88.5

I get:

Tuning to 88.50 MHz
Invalid freq '138650000'. Current freq out of range?

When scanning:

radio -s

produces no output whatsoever before going to the curses interface set
at frequency 138.65.

3.2.0-4-amd64

I could try the liquorix kernel (3.8) if you thought it might help.
