The FSF is going to be easy to persuade to use bitcoins. Lets send them a letter (adapted from CCC one).
Suggestions and pledges are very welcome.

Dear Free Software Foundation,
The Bitcoin community appreciates your efforts to protect computer users freedom to use their computers as they wish.
Bitcoin <
http://bitcoin.org > is a new free software P2P cryptocurrency system, published under the MIT license. We hope it will allow users to use their money as they wish, free from government intervention and the need to use proprietary software systems found in banking and payment systems.
There are already several enterprises and individuals in the Bitcoin community and growing. We have donated already donated X BTC (~X USD) to the EFF and have pledges to donate X BTC (~X USD) to you if you accept Bitcoin donations.
Warmest regards,
The Bitcoin community.
