Woops my fault. I meant to check during runtime from a
binary. Couldn't GGI installation procedure put a
drivers.lst or something like that in the ggi directory in
the include dirs. (Bad hack, I know.) Someone with a more
eloquent way should jump right up and tell me. :)

A long time ago I asked whether or not I could check for a
cursor during runtime in GGI. I need to know whether I need
to render it myself(svgalib target) or if I can use a
pre-existing one (X11 target).
