Reverting the HDTV resolutions patch (http://cvs.savannah.gnu.org/viewvc/vgabios/vbetables-gen.c?root=vgabios&r1=1.5&r2=1.6 ) makes the problem to go away. Note that with the patch applied, the mentioned ubuntu image which I used for testing -- > I'm attaching Xorg.log from ubuntu 11.04 guest (live cd) booting in > qemu-kvm 0.15, in case it can help.

Without that patch, it boots into full-screen mode where on the left there's a list of language choices and on the right, larger part, two large buttons "install" and "try". With this patch in place, it boots into a very small screen showing only language selection, and when done, that screen gets replaced with the install menu. I can only guess it is done in order to fit everything in a small screen, so the installer is unable to set the screen resolution properly. Without the HDTV patch, the maximum resolution shown by this very test guest is 1024x768, so it is difficult to say what is the actual improvement. I tried to remove 1280x768 mode (introduced by this patch), and now my test guest behaves sanely at 1280x720 resolution (choosen by default). But to be fair, I've no idea what to blame. vesa driver? seabios? qemu? The added modes looks correct, but the resulting behavour is obviously not.
