As far as I understood, we're trying to port Linux and
applications that are already available for it to the DS. We're not
trying to write tons of new code ourselves that makes use of the
features of the DS in a special way.

GPM is a standard feature for most Linux systems, which means that it
can be used by a lot of available apps (e.g. links, which we already
have running). GPM is also familiar to Linux users. They'll know what it
can and what it cannot do for them. All it needs is another 2 buttons.
Adding them is much less work than what you proposed.

If you need a PDA-like interface, either come up with one, or just
buy a PDA. The Zaurus has Linux pre-installed.
