Can others please test and report whether the patch fixes the 
viewport placement problem for them?  Especially on other chips 
than a KM400.

There still is a remaining problem, though: grab the lower edge of 
the glxgears window and move the cursor all over the screen; sooner 
or later the square around the cursor becomes an opaque white 
square, sometimes with inverting patches.  This is most easily 
reproduced when the glxgears window is not in a corner.

When grabbing the lower edge of the glxgears window while this edge 
was flush with the bottom of the screen, then moving the cursor 
around will even scratch over the entire top 20% of the screen.
