Yes, these are the drivers you may need :)
You can activate / prepare them in nutconfig by configuring the options 
under Architecture/AVR/HD44780 Driver and Bus.

Just use the wiki or the manuals:
http://www.ethernut.de/nutwiki/Main_Page
http://www.ethernut.de/pdf/enswm28e.pdf
And the rest of the pdfs here:

But what do you mean with FM? For me it's frequency modulation...
