title: Change resolution(screen size) on Android ICS virtualbox issue
body: <p>I have built android ICS(4.0.3) for virtualBox. And it runs well with default resolution 800x600. 
  However, when I change the virtualbox resolution to non-default ones, say 1280x800.
  Then I get error "Unfornately, System UI has stopped". And the system hangs there. In addition, I cannot even connect to this device to see the logs when resolution changes.</p>
  
  <p>Would you please give me some help? Thanks.</p>
  
  <p>BTW,
  The way I change resolution is suggested by <a href="http://www.buildroid.org/blog/?p=107" rel="nofollow">Buildroid</a> ----</p>
  
  <p>First  add a “custom video mode” to .vbox configuration file : Add the line 
  &lt; ExtraDataItem name=”CustomVideoMode1″ value=”1280x800x16″/> 
  just after the already present “ExtraDataItem” entries.
  Modify the linux kernel options to replace the existing vga=xxx by a vga=ask
  Then, choose the expected resolution.</p>
