Hi Stefan,

I gave v4 a whirl, and found that the graphical issues are resolved when
running qemu-system-ppc with OSX 10.2 and 10.3 guests. Also 10.5 guest
seems OK. There are some issue left (or even new), however, on OSX 10.4:
Most of the info in the "About this Mac" window is not shown, and there is
a black rectangle in the upper  right corner of the screen where access to
the spotlight search facility should appear.

Should I prepare a 10.4 image for you like the 10.3 image?

Best,
Howard
