Title:
  [RV515] screen flickers in lucid lynx beta1 [Needs pll quirk]

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  As already reported by other users in bug reports #544662 or #543045,
  my laptop screen flickers in Ubuntu Lucid Lynx beta1. This can happen
  at boot time of after a few minutes, but when it begins it stays until
  shutdown or reboot.

  As for other users, this issue is solved by passing "radeon.new_pll=0"
  parameter to the kernel at boot time, or by passing "new_pll=0"
  parameter to "radeon" kernel module.

  My laptop is a Dell Inspiron 6400 (aka E1505), an ATI Radeon Mobility
  X1400 video adapter and a 15.4" 1680x1050 panel. (See attached files
  for details)
