Can you clarify, by "FM Radio" do you mean broadcast FM (87.5-108 MHz)?

In terms of bandwidth, 3Msps sounds sufficient, but you'll have to
implement an FPGA design which communicates with GNU Radio. Instead of
starting from scratch, you can try to start from the USRP2 sources
and apply modifications for your particular board.

To get an idea of what this is like, you can look at similar changes
we made to USRP1. There are two repos (FPGA and GNU Radio) hosted at
http://git.thinkrf.com/, look at branches ending in "wsa". It's a bit
of a mess at the moment, but I'd be happy to answer any questions.
