Long ago, when all we had was 32bit Slackware and I was working on realizing the 64bit variant of Slackware, I created a '64bit' lilo bitmap with the Slackware  logo, to make it more obvious to your friends that your computer is booting 64bit Slackware and not some obscure other distro. Lilo is getting a bit old in the tooth though.
