So do I get it right that the only reason of the problem you were 
seeing was that in the 2.6.27 kernel you have compiled usbhid module, 
which was then used for driving your mouse,but in 2.6.28-rcX you 
compiled and used 'usbmouse' instead, and therefore this is not a 
regression?

Shouldn't usbmouse support two-dimensional mice as well?

Yup, but that's a separate issue on my TODO. I first want to know whether 
this is a regression or not.

Thanks,
