>This enables resume from suspend level S3 by asking the Radeon chip if it
>thinks it has no memory.  If so, the card is re-POSTed via the int10
>interface.  Reportedly enables the driver to work for this type of
>suspend/resume cycle on Dell D600 laptops (Dell D800s as well, if the video
>BIOS is patched to 4.28.20.31.C1 or later).  See Debian Bug #234575.
