I use GGI for other things (GGL development, for example) but now
I'm porting my graphics library from DOS to Linux (almost done), because I
want to code an Intro (of demoscene), and when coding demos/intros, It's
very important not to use libraries not coded by myself.

Ahh, ok, anything but 0... I thought that it should return -1 on
error as ioctl manpage says...
