Yes !!! You don't need to buy a new Palm, to wait for the new model that uses Linux as its OS...you can simply download some binaries, follow some easy steps and....woohooooo...you have Linux in your Palm !!!!
I have a Palm TX and it works really good, it doesn't have Wifi support yet but overall it's great and promising.
Try this out ! (but make a backup of your data before, just in case).
