Reflashing definitely would tell you if you have a hardware problem, but first you might just want to take slightly less drastic steps. Remove the FM Faker, whatever that is, and try again.

Also, what do you get from this command:
cat /sys/class/i2c-adapter/i2c-2/2-0063/power_level

That file is what determines the power level of the transmitter, and by default it is 113. I have a script to set mine to 118. Be careful to not fo above a certain level (I think it is 121).

Finally, what do you get from:
md5sum /lib/modules/2.68.28-omap1/fmtx-si4713.ko
