I think it is fine to assume that these devices that do not have a built-in
screen but support one by adding a graphics device can have a more or less
arbitrary resolution. That means that you assume a common resolution like
1024x768 and if you really have a special need you would override these values
anyway. For most devices which usually have no screen or a built-in one you
would be quite safe with one setting. For the others just choose a big default
which should bee correct in most cases and for things like background images it
is usually better to ship a big one and scale it down instead of shipping a too
small one.

That's fine as long you do not have this set if you do not have the screen
feature enabled, otherwise you might pull in big backgrounds and similar stuff
for no reason.

Exactly... and on rotatable displays you need some support from the applications
anyway.
