Title:
  Video not initialized correctly on resume with Intrepid/amd64 RS482
  [Radeon Xpress 200M]

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Acer Aspire 5100 laptop is able to suspend/resume correctly with i386
  Ubuntu (Hardy, Intrepid).  It *almost* works with Intrepid amd64.
  However, within a few seconds of resume the screen starts to flicker
  as if the display signal is out of sync.  This gets worse over the
  course of a minute or so, until the display is essentially unreadable.

  This is with the free ATI driver.  I tried a few suspend/resume cycles
  with the non-free driver and it works fine.
