[maemo-users] Is it possible to change screen orientation with N800?

[From: Thomas Gaudin]

Hi,

I was wondering wether it is possible to switch from landscape to 
portrait display mode with the default setup.
If it needs customization to achieve this, which steps are needed?
Finally, is it also possible to force the display to be always in 
portrait mode, without a normal user (not root) can change it?
Thanks for your answers, any pointers are warmly welcome!

Thomas
