BSD Licensing Compatibility

[Martin <martin.kelly4000%gmail.com@localhost>]

Hey,
I am looking at creating a derived File system from currently available open-sourced File-systems. My big question is license compatibility, as i don't want to start the project only to find that the source i have used is not under a compatible license with the other source/s.

The current sources i am looking at are licensed under the following:
BSD License
GNU GPL version 2
GNU GPL version 1

I understand you can license something under a multiple licenses, but i was kinda hoping to eventually release it under one of the BSD licenses.

Regards,
Martin
