Same problem here (Xorg-1.4.0 kdrive server Xfbdev) ... I had a quick look 
into the code, I think this happens in src/kinput.c KdEnqueuePointerEvent().
Here, the transformation matrix is applied to the coords, swapping coords if
necessary (depending on rotation) and then basically queued as events.

In case of a rotation of 90 degs -> x = -ry, which I guess is clipped to 0 
later on in GetPointerEvents() (dix/getevents.c), thus resulting in zeroing 
the x-axis....

Basically I guess besides applying the matrix on the coords, depending on 
coords < 0 the max axis values have to be added to yield correctly 
transformed coords


I just started to look into xserver code, so apologies if I am totally wrong!
