Why does a programs terminate immediatelly with "svgalib: Cannot get I/O
permissions."?

svgalib programs need to be run as root. This means that either the user that
runs them is root, or, if running by normal users is desirable, the program
needs to be 'suid root', which means: the program must be owned by root (chown 0
program) and the suid bit needs to be set (chmod u+s program).
