** Description changed:

  Binary package hint: xorg
  
  The bug is KMS modeset=1 measured 22% slower than vesa with video
  intensive GtkPerf is from Ubuntu synaptic, and 12% slower than
  modeset=0.  At least for this benchmark ubuntu is faster with vesa than
  with the specific ati drivers.
  
  Does anyone know how to get launchpad to handle columnar data?  
  There are 5 columns of data here.
  
  Measurements are from IBM Thinkpad T40 with ATI Radeon Mobility 7500.
  Col 1 is measurements with xorg driver vesa.
  Col 2 is nomodeset no KMS xorg ati driver 6.12.99+git.....
  Col 3 is modeset=1 KMS xorg ati driver 6.12.99+git.....
