Jason Gerecke, another linux wacom developer, happened to have a Graphire4 to test with. Chris Bagwell's patch (attached) against a recent kernel git was tested by Jason and works. It should be submitted upstream to the kernel's linux-input at some point.
Connor and kopiwie, I don't know when and if Ubuntu would back port this fix into Natty. There seems little chance of regression with it. In the meantime you could use input-wacom-0.11.0 for its wacom.ko. Compiling it is also described in the HOW TO linked above. Jason said it worked for him because it already had the line:
input_event(input, EV_MSC, MSC_SERIAL, 1);
in it. So you could try it and see if it does the job. You may not need to add the other line if it works ok for you.
We have a fix.
