I tried both the ATI proprietary driver and the one from xorg. With both
resume does not work. Also tried the Option "VBERestore" "true" in
xorg.conf. It made no difference.
Does the command "vbetool vbestate save" return an error on your laptop?
See man vbetool for more information about this app.

Same here. Tried to add various scripts in /etc/pm/{actions,events} and
also installed acpitool and tried acpitool -s. Suspending always works,
resume does not. No blinking HD led and no power to the screen. When I
do a hard reset and the laptop reboots I always see the kernel say there
was no suspend signature found.

If you find something I would appreciate it if you could post your
findings.

My card reader is not working yet but there are some encouraging
results. Not thanks to TI's stubborn refusal to release documentation
for the card reader's chipset. Sigh, when will TI and Broadcom catch up
to reality.
Anyway, I would love to see this laptop suspend & resume correctly. Hope
there will be some progress with a new kernel and/or pm-utils rpm.
