I've been experimenting similar problems on my Thinkpad, no Nvidia onboard, in 
fact, i read some reviews a week ago, and seem to be several problems with 
suspend when we're talking about Nvidia.

By the way, when my laptop came from the suspend, all was running (xmms, for 
instance), so i thought that maybe Xorg problem, not suspend at all.

I added:
  Option "VBERestore" "true"

On xorg.conf device options and, at least, for me, works fine.
Also, i ought to say that i'm using one customized script to suspend my 
laptop, here you're:

#!/bin/sh

# discover video card's ID
ID=`lspci | grep VGA | awk '{ print $1 }' | sed -e 's 0000:@@' -e 's@:@/@'`

# securely create a temporary file
TMP_FILE=`mktemp /var/tmp/video_state.XXXXXX`
trap 'rm -f $TMP_FILE' 0 1 15

# switch to virtual terminal 1 to avoid graphics
# corruption in X
chvt 1

# write all unwritten data (just in case)
sync

# dump current data from the video card to the
# temporary file
cat /proc/bus/pci/$ID > $TMP_FILE

# suspend
echo -n mem > /sys/power/state

# restore video card data from the temporary file
# on resume
cat $TMP_FILE > /proc/bus/pci/$ID

# switch back to virtual terminal 7 (running X)
chvt 7

# remove temporary file
rm -f $TMP_FILE


Hope this help
