I've removed the vbetool package. This solves the freeze problem,
but the screen still remains off after resuming (I can still work
remotely via SSH).
The problem occurs with both suspend to RAM and suspend to disk
(pm-suspend and pm-hibernate).
I've tested the following script found on
http://en.gentoo-wiki.com/wiki/Dell_Latitude_E6x00#Suspend_.28RAM.29
but again, the screen remains off after resuming.

#!/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

BTW, here's what I get in the log messages:
