Hmm.. I get a nonzero value any way I try it.

ln -s /lib/libvga.so libvga.so
with "fm = open_dll("./libvga.so")"

fm = open_dll("libvga.so")

fm = open_dll("/lib/libvga.so")

All of these work fine for me.  I would recommend leaving libvga.so in
/lib or /usr/lib and using "libvga.so" without a path, and let ld.so do
the work in finding it.

Typing "nm libvga.so" on my machine gave "no symbols" as you say, so I
tried "nm -D libvga.so" (-D for dynamic) and it spewed forth a great many
symbols so it seems to be ok.

You may want to check and make sure that SVGAlib is installed properly, or
download the latest version from www.svgalib.org and install it.  Another
thing to try is rebuilding the shared library cache "/etc/ld.so.cache"
using "ldconfig".

And if you do get it to link to the library successfully, don't forget to
run it as root so it will have proper permissions to setup the graphics.
