Patch to add get_dimensions to the console-client

[marco]

Hi,

Included with this mail is a patch to add a new interface for display drivers
and the the implementation for the VGA and ncurses driver.

I need this for adding support for non 80x25 resolutions and it is
extremely usefull for screensaver support.

Thanks,
Marco
