Kernel Projects

Hi, Does anybody know if there is a program to offer small (or big) kernel projects to students or someone who are interested in? I'm looking for programs like Google Summer of Code or http://kernelnewbies.org/KernelProjects I'm interested to contribute with kernel patches, but I don't know how and where to start it. I will be glad if someone give me ideas and/or suggestions. Thanks! *--* *Julio Cesar Faracco* *University of São Paulo - Brazil*
