Perhaps the cursor speed which I use with Inkscape is too slow.
I'm not sure what options your tablet driver offers, but with Wacom's you can use the tablet in either 'Pen' or 'Mouse' mode. I find Pen mode unusable because it's so slow: it's meant for pixel-level editing and drawing, so not suitable for mouse replacement.
If your tablet doesn't offer a mouse mode, then try boosting the speed/acceleration to max.
