Just want to note that boost-script integration isn't that urgent IMO. I checked the custom FMTXD file from here:

http://talk.maemo.org/showthread.php?t=60567

...and with the newest FMTXD file for PR1.3 its easy to install and much better than the boost-script. All frequencies unlocked, power strenght always set to 120 and there is no need to disable/enable the transmitter when you plug in a charging cable.

So download FMTXD from here
http://jacekowski.org/

and use FileBox (file manager with root access) to copy the file to /usr/sbin (don't forget to backup the original one).

Then open x-terminal and use the following commands:

sudo gainroot
chmod +x /usr/sbin/fmtxd
killall fmtxd
fmtxd -d

(More information to this in the linked thread)

That's it, 76.1Mhz->107.9Mhz available and always full-boosted. Right now i have FM RDS Notify in addition to friendly fm on my desktop (fully covered by media player widget) for RDS info. This is the best solution for me right now.
