Ah, yet another story - I don't know if it's supposed to work with that.
It would be a good idea to mention such information in your posts, as
these days 'iBook' usually refers to one of the newer machines.

xdpyinfo shows the root window dimensions, which never change normally.
xvidtune -show will show the current mode.

fbset :) Hint: apt-cache search fbset

It won't help though as the atimisc X driver ignores the framebuffer
