This seems to be a general issue with the cirrus driver in the kernel. I found the following post in the qemu forum, which provides an xorg.conf for a 1200x900 resolution: http://qemu-forum.ipi.fi/viewtopic.php?f=10&t=4631
Regrettably I did not manage to get any higher. Using '-vga std' is no help either, because the ubuntu guest hangs on boot when trying this option.
