Try the quirk site which can help you analyze the problem and fixing it:
Recommendations based on my experience with an Acer TM6465 laptop:
1) do not use "vga=..." when booting the laptop. Remove it at boot or
from grub.conf. If you get suspend/resume working you can try to turn
it back on and see if it still works
2) run the quirk-check.sh script for recommendations. Get it here:
If you use the fglrx driver the script will complain and abort so
switch to the open driver before using it
3) answer all the question on this webpage and follow the advice. For
example if that webpage recommends you try "--quirk-s3-bios" or
"--quirk-s3-mode" this means that you boot your laptop (without
vga=...) and with the open driver, not the proprietary fglrx driver,
login to your graphical environment, open a terminal and as root type
# pm-suspend --quirk-s3-bios
or if it does not work
# pm-suspend --quirk-s3-mode
4) you can only use the fglrx driver and have working suspend/resume if
you disable the DRI functionality in the fglrx driver. Obviously it
doesn't make sense to use a proprietary driver if you can't use the
DRI part so I recommend you switch to the open one.
if you really must use fglrx then disable DRI in /etc/X11/xorg.conf:
Option "OpenGLOverlay" "off"
Option "VideoOverlay" "on"
Option "no_dri" "yes" # <----- turn off DRI
Do realize that without DRI the performance of 3D apps like games
will be terrible so you might as well use the open driver.
6) if everything fails, download Fthe edora 8 Test 3 Live image, boot it
on your laptop and check if suspend/resume works. If it does at least
you know you have another option.
Hope this helps.
