you should note that acpi-support is deprecated, you need to use /etc/pm/config.d/ ... try with adding a file there with the following line:
ADD_PARAMETERS="--quirk-vbemode-restore --quirk-s3-bios"
that helped on some intel cards i have seen in the past ... also if the screen comes up black, did you try hitting brightness up or down ? it could be that the backlight just didnt get switched on...
