My machine: Acer Aspire X3810
OS: Fedora 18 installed from the live KDE spin
Desktop Environment: KDE 4.9.5
Tablet: Wacom model PTZ-930
I was asked about this. I wont have a lot to say because it mostly just works - but I will outline what I've done. The mostly comes from the fact that the one hang up is sort of a big deal but not a showstopper. When I initially plugged in the tablet it did not work and was not noticed by the kde configuration tool. After logging out and back in, the configuration tool saw it but it still didn't do anything. After a reboot, with the tablet plugged in, everything is fine.
I did install some packages not picked up from my initial install. I don't think they were necessary but I got them. They are all from the repos. The one already installed was xorg-x11-drv-wacom. I added kcm_wacomtablet (this is the gui config utility), libwacom and libwacom-data.
Once I did the little reboot dance above I could move my stylus around above the tablet and my mouse pointer would move.
Then I fired up Krita and drew some stuff. In The Gimp I needed to go into Edit -> Input Devices and turn on my various Wacom things. They were set to disabled. Once I did that it works great - with the varying levels of sensitivity to pressure and all that good stuff.
If I unplug the tablet and plug it back in - KDE kicks of notifications that it has been removed and that it has been added back in, but it will not work. Back to reboot land. So - not ideal but really not the end of the world. I don't know what the issue is but I have similar problems with my usb headset. I can unplug it and plug it back in - if it was in when the system started. If not, it's a no go. So something with usb and getting it all to work isn't right. I can live with it.
