I found the bug, it is specific to cyblafb.

 The problem is that the 16x30 font causes the cyblafb imageblit to fall 
back to
cfb_imageblit for rotation 1 and 3 while the accelerated copyarea 
function is
still used. That breaks the private sync mechanism of cyblafb and causes 
the
erroneous behaviour.

 I´ll publish a patch soon.

cu,
 Knut
