This may be a bug in the debian-installer. I can't reproduce this with the live CD. When installed from the alternate CD or mini iso, XKBOPTIONS="lv3:ralt_switch" is added to /etc/default/console-setup. Commenting out that option and rebooting fixes the issue, but I'm unsure why that was set in the first place.
