xorg-x11-drv-wacom-0.10.99-1.20110315.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/xorg-x11-drv-wacom-0.10.99-1.20110315.fc15
bug seems to be back on F15-Beta-TC1
Lukas, that's because package updates require positive feedback in order to be pushed out. There was an update link supplied in comment 3. In the future, if you would help us out by providing feedback on updates, it would help us get package fixes to stay. We got someone to provide feedback just now, so I've gone ahead and marked this as stable, so will appear soon. I'm proposing this for F15Beta based on the following Alpha criterion: 15. ...a system installed according to any of the above criteria (or the appropriate Beta or Final criteria, when applying this criterion to those releases) must boot to a working graphical environment without unintended user intervention.
sorry my bad. I have to remember that whining about bugs isn't enough :)
