Title:
  Thinkpad T30 LCD does not turn off during suspend to ram

Status in “acpi-support” package in Ubuntu:
  Invalid

Bug description:
  My Thinkpad T30 laptop is configured as dual boot system with Debian
  Etch and the Hardy Heron final release.

  After booting into Hardy Heron, when doing suspend  to ram from either
  the gnome power manager, or using the Thinkpad function keys, the lcd
  display does not turn off.  It goes blank for a moment, and then
  starts to turn greenish; the discoloration starts at the bottom the
  display and gradually up from the middle of the display.  If I close
  the lid, the display still remains on.  The laptop will still resume
  from suspend.

  I have tried setting "RADEON_LIGHT=true" in /etc/default/acpi-support,
  but this does not alleviate the problem.

  Debian Etch, which was installed first on the laptop, does not exhibit
  this behavior at all.  The display turns off when I suspend to ram
  from kpowersave, or using the function keys.
