After this patch anyone with more than 4 reg tablets/2 multimode(dual-tracking) tablets connected at once may have problems. I thought that it would be rare anyone would have more tablets than that so let me know if I'm wrong. Without this patch 3 reg tablets/1 multimode tablet are fully supported.
Erm that is to say support in mainline wine is for 3 reg tablets/1 multimode with this patch support is increased to 4 reg tablets/2 multimode. Cursor detection is better with this patch than mainline as well.
