I haven't gotten 10.0 but I think that they setup is generally the same. In YaST, there's a option to edit your peripherals. Within there there's settings for the tablet. From there you can setup the active area for your tablet. I did this for Graphire 3. I have since upgraded to Graphire 4 but haven't been using my tablet with a linux OS.
I hope that you is of some help for you. I'll be updating one of my boxes to Suse 10 and will be using a tablet on it. I'll let you know if what I try works.
