You can get the SDK <a href="http://www.palmos.com/dev/tools/sdk40.html" target="_blank">here</a> (get the Linux one). I haven't played around with them, but I would think you could get them to work with PB, if you can come up with the right Project Template. If not, I'm sure you could use the cli.
Good luck! Let us know how it goes. I (and I'm sure others) would be interested in developing for Palm using PB.
