Yes, your old xorg.conf has got all the normal wacom stuff commented out 
(but it looks as though it never had the 'pad' section that makes the 
circular pad work).

In 8.04, my xorg.conf has these four wacom sections near the top:

Section "InputDevice"
   Driver        "wacom"
   Identifier    "stylus"
   Option        "Device"        "/dev/input/wacom"
   Option        "Type"          "stylus"
#  Option        "ForceDevice"   "ISDV4"           # Tablet PC ONLY
#  Option        "USB"           "on"               # USB ONLY
EndSection

Section "InputDevice"
   Driver        "wacom"
   Identifier    "eraser"
   Option        "Device"        "/dev/input/wacom"
   Option        "Type"          "eraser"
#  Option        "ForceDevice"   "ISDV4"           # Tablet PC ONLY
#  Option        "USB"           "on"               # USB ONLY
EndSection

Section "InputDevice"
   Driver        "wacom"
   Identifier    "cursor"
   Option        "Device"        "/dev/input/wacom"
   Option        "Type"          "cursor"
#  Option        "ForceDevice"   "ISDV4"           # Tablet PC ONLY
#  Option        "USB"           "on"               # USB ONLY
EndSection

Section "InputDevice"
   Driver        "wacom"
   Identifier    "pad"
   Option        "Device"        "/dev/input/wacom"
   Option        "Type"          "pad"
#  Option        "USB"           "on"                  # USB ONLY
EndSection

But in order to work, it has to have the wacom in the ServerLayout 
section *at the end* of the file, thus:

Section "ServerLayout"
   Identifier	"Default Layout"
   screen "Default Screen"
   InputDevice   "stylus"  "SendCoreEvents"
   InputDevice   "eraser"  "SendCoreEvents"
   InputDevice   "cursor"  "SendCoreEvents" # For non-LCD tablets only
   InputDevice   "pad"                      # For 
Intuos3/CintiqV5/Graphire4/Bamboo tablets
# InputDevice   "touch"   "SendCoreEvents" # Only a few TabletPCs 
support this type
EndSection

However, this is a problem in Jaunty, which - as the comments in your 
old xorg.conf file show - is now using HAL instead of the xorg.conf 
method.

You'll have seen that <https://help.ubuntu.com/community/Wacom> says,

"Of course, it is always possible to revert to the old configuration 
method with /etc/X11/xorg.conf, but you will loose hotplugging support"

but when, on my Jaunty machine, I added the ServerLayout section, X 
wouldn't start at all , and the boot process popped my out into a 
text-based login, from where I was able to restore may backed-up 
original xorg.conf (don't forgt to do a backup before you change anything!).

In fact, the proper method for Jaunty appears to be to use a cusotm .fdi 
in /etc/hal/fdi/policy/, as the Ubuntu Community HowTo above indicates.

But... but... I was trying to install much newer hardware, with a 
linuxwacom driver that may not be playing nicely with the Jaunty kernel. 
  You're using hardware for which the driver does seem OK.  I suggest 
you create a backup of your /etc/X11/xorg.conf, then add (or edit in) 
the four wacom sections, add the ServerLayout section at the end, and 
reboot.  If X fails to start, you can always use the command line to

sudo cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf

(I am assuming here that you've got the right driver and kernel module 
installed.  But as I think you said the stylus was working, I guess you 
must have.)

HTH

(and let us know how you get on!)
