Ну вот, можно не торопиться, скоро P1 сами все сделают (шучу, надежды на портирование для старого железа мало). Вчера P1 анонсировали использование Линукс как основы для разработки следующих версий PalmOS. Судя по вопросам-ответам, принцип похож на связку Darwin+Aqua у Apple.

Linux community questions
Q. How will Palm OS® for Linux be implemented?
A. It will be a software layer on top of the Linux operating system.
Q. Does this mean Palm OS will be open sourced?
A. We expect that we'll be contributing some of our technologies to the open source community as a part of this change. The user-visible parts of Palm OS (user interface, PIM applications, etc) and the Palm OS middleware will be a separate software layer on top of Linux, and will not be open sourced.
Q. Will PalmSource be subject to the GPL (General Public License)?
A. Changes and enhancements that we make to Linux will be subject to the GPL.
Q. How do you intend to participate in the Linux community?
A. We expect to participate in Linux community activities, and are actively investigating appropriate groups to join.
Q. Will Palm OS for Linux be able to run on a variety of Linux distributions (i.e.: standard versions of Linux distributed by other companies)?
A. We plan to make our Linux layer compliant with open standards, so it should be able to run on other Linux distributions.
Q. Does that mean you'll be offering it for sale as a separate layer?
A. Most mobile devices are sold as complete solutions, so the most likely scenario is that the Palm OS layer could be bundled by hardware companies that have chosen other Linux distributions. This is the sort of partner flexibility Linux creates, and we intend to support it.
Q. Once Palm OS is implemented for Linux, would you consider porting it to new types of devices?
A. The ultimate design target for Palm OS is all phones and mobile devices. We think the flexibility of Linux will let our operating system run on a wider variety of potential hardware than it is on today.
Q. What will be your business model for Palm OS® for Linux? Some Linux layer companies give away their layer and charge software developers to create applications.
A. We plan to continue with the same business model as today -- developers can create programs at no charge, and we charge licensees to include our software layer in their products.
Q. Will I be able to download Palm OS® for Linux and run it on my Zaurus or other Linux devices?
A. That's not in our initial plans, but we're interested in your feedback on whether it would be of interest.
Но - она (Шарповский вариант), да и Opie тоже и X-сервер в pdaXrom'е (ИМХО), очень активно пользуются специфическими устройствами в /dev и псевдофайлами в /proc, которые поддерживаются только Шарповским ядром и, следовательно есть только на Шарпах. Так что она таки аппаратно зависима, хотя и является приложением, а не частью ОС.
