Patch provided by mithro

I've included 2 patches need to make opie support on the fly screen
 resolution changing. This is done with the following,

 qcop "QPE/System" "setCurrentMode(int,int,int)" 480 640 16

 This is good for running applications in compatibility mode on the C700.
 As you can see there isn't much to these patches.
