Thanks for this!! I got it working on 12.04 just like I had it on 11.10 
However, I've manually editing the script you linked to and will post it below. I think my version is much more professional looking and clean. Also, make sure you grant read/write/execute permissions to "other" once you put the file in home/scripts or other wise sysmon will only display "(no output)".
Code:
#!/bin/bash
#settings:
netspeed=true
ram=true
cpu=true
#-------------------------------------------------------
#---------------- initialize ---------------------------
rm /tmp/.sysmon > /dev/null 2>&1
dstat --net --mem --cpu --output=/tmp/.sysmon 1 1 > /dev/null 2>&1
#----------- up/down speed -----------------------------
if [ $netspeed = true ]; then
upspeed=$(echo $(cat /tmp/.sysmon | tail -1 | cut -d ',' -f2)/1024 | bc)
upkbmb=$(if [ $upspeed -gt 1024 ]; then
up1=$(echo $(cat /tmp/.sysmon | tail -1 | cut -d ',' -f2)/1024/1024 | bc -l)
echo $up1 | head -c 4
else
echo $upspeed | head -c 3
fi)
downspeed=$(echo $(cat /tmp/.sysmon | tail -1 | cut -d ',' -f1)/1024 | bc)
downkbmb=$(if [ $downspeed -gt 1024 ]; then
down1=$(echo $(cat /tmp/.sysmon | tail -1 | cut -d ',' -f1)/1024/1024 | bc -l)
echo $down1 | head -c 4
else
echo $downspeed | head -c 3
fi)
#---------------- up/down speed unit --------------------
downunit=$(if [ $downspeed -gt 1024 ]; then echo "MB/s"; else echo "KB/s"; fi)
upunit=$(if [ $upspeed -gt 1024 ]; then echo "MB/s"; else echo "KB/s"; fi)
fi
#------------------- CPU % used -------------------------
if [ $cpu = true ]; then
cpufree=$(cat /tmp/.sysmon | tail -1 | cut -d ',' -f9)
cpuused=$(echo 100-$cpufree | bc | sed -e 's/\..*//')
fi
#------------------- RAM % used --------------------------
if [ $ram = true ]; then
memused=$(free -m | grep buffers/cache | tr -s ' ' | cut -d' ' -f 3)
memfree=$(free -m | grep buffers/cache | tr -s ' ' | cut -d' ' -f 4)
memtotal=$(echo $memused+$memfree | bc -l)
memusedpercent=$(echo 100-100*$memfree/$memtotal | bc)
fi
#------------------ The Indicator Sysmonitor actual output -
echo $(if [ $cpu = true ]; then echo CPU: $cpuused% \|; fi) $(if [ $ram = true ]; then echo RAM: $memusedpercent% \|; fi) $(if [ $netspeed = true ]; then echo ↓ $downkbmb $downunit ↑ $upkbmb $upunit; fi)
