Okay, here's the new code based on this:

# use fbcon kernel functions?
USE_FBDEV=
if [ -e /proc/fb ]; then
  FB_TYPE="$(awk '{print $2}' < /proc/fb)"
  # did we actually get back anything?
  if [ -n "$FB_TYPE" ]; then
    case "$FB_TYPE" in
      OFfb|VESA)
        # generic framebuffer that doesn't support UseFBDev
        ;;
      *)
        # other framebuffers do support UseFBDEV
        USE_FBDEV=yes
        ;;
    esac
  fi
fi

if [ -n "$USE_FBDEV" ]; then
    auto_answer db_input high xserver-xfree86/config/device/use_fbdev "true"
else
  db_get xserver-xfree86/config/device/use_fbdev || debug_report_status "db_get xserver-xfree86/config/device/use_fbdev" "$?"
  if [ "$RET" = "true" ]; then
    debug_echo "xserver-xfree86/config/device/use_fbdev is \"true\" but /proc/fb does not exist, is empty, or reports a framebuffer type with which UseFBDev cannot be used; setting template to \"false\""
    db_set xserver-xfree86/config/device/use_fbdev false
  fi
fi

Comments?
