fm-boost: Not seeing any effect

Wonder what this app does as even without running it:

Nokia-N900:~# cat /sys/class/i2c-adapter/i2c-2/2-0063/power_level
120

whereas fm-boost script tries to set it to 118?

Anyway, after running it I still see the value not changing to 118. It
just remains 120 and there is no change in transmission range.

I think fmtx default power was changed to 120 in kernel-power or CSSU
at some point. If you're using those then the fm-boost package is
obsolete.

Yes in kernel-power v49 was default power_level changed to 120.
So then fm boost package can removed.

Also in PR1.2 or 1.3 Nokia kernel the power setting was locked a bit,
but I don't remember the details.
