    installer: welcome: Warn when uvesafb gets used.
    
    There will be false positives: Because the Guix installer uses the
    kernel argument modprobe.blacklist=radeon,amdgpu and some AMD graphics
    actually work okay according to h-node, these users will get a
    false alarm.
    
    * gnu/installer/newt/welcome.scm (run-welcome-page): Warn before showing
    the welcome page.
