I have an IBM ThinkPad X31 (2672-XXH), also with a ATI Radeon (ATI Technologies Inc Radeon Mobility M6 LY). While I do not get the high pitched noise, I do see the problem with the LCD backlight not powering off during S3. I have to use radeontool [1] to power off the LCD backlight before going into S3 and reverse this procedure when the laptop wakes up from S3. Perhaps the in-kernel radeonfb driver could be modified to allow powering down the LCD backlight before entering S3?
