This looks like an xorg or udev problem. You’ll need a file in
the /etc/udev/rules.d directory. The usual name is 65-xorg-wacom.rules
(needs to start with a number determining when it’s read and end
with .rules) and the following four lines should detect Wacom tablets
correctly.
ACTION=="add|change", SUBSYSTEM=="pnp", ATTR{id}=="WACf*",
ENV{NAME}="Serial Wacom Tablet"
ACTION=="add|change", SUBSYSTEM=="pnp", ATTR{id}=="FUJ*",
ENV{NAME}="Serial Wacom Tablet"
ACTION=="add|change", SUBSYSTEMS=="pnp", ATTRS{id}=="WACf*",
ENV{ID_INPUT}="1", ENV{ID_INPUT_TABLET}="1", ENV{x11_driver}="wacom"
ACTION=="add|change", SUBSYSTEMS=="pnp", ATTRS{id}=="FUJ*",
ENV{ID_INPUT}="1", ENV{ID_INPUT_TABLET}="1", ENV{x11_driver}="wacom"
Save to /etc/udev/rules.d/65-xorg-wacom.rules and check that it is
readable by everybody.

If this file is in place you should can get the Wacom tablet working by
restarting X (or rebooting). I don’t know if the wacom module will get
loaded automatically. You can check with

$ lsmod | grep wacom

which will give some output if the module is loaded. If not

$ sudo modprobe wacom

should make the tablet accessible to X (and gimp).

The 65-xorg-wacom.rules file comes from
https://bugs.launchpad.net/ubuntu/+source/xf86-input-wacom/+bug/522318
which also gives some examples of using udevadm to find out what udev
sees and makes available to X.

The /etc/X11/xorg.conf file can be very simple. Mine has no settings for
the wacom tablet.

I guess all of this will be fixed in 10.10. The problem seems to be a
combination of the new xorg/udev setup in Lucid and a tablet that
requires a very recent version of linuxwacom.
