Sounds similar to an issue I've heard where those trying to get SDL to work
with the framebuffer cant because SDL demands X11.

I recommend compiling SDL w/o svgalib support, and then modifying sdl.c
to report the error. Specificly, change sdl_display_init so this line

fprintf(stderr, "Could not initialize SDL - exiting\n");

becomes this line

fprintf(stderr, "Could not initialize SDL - %s\n", SDL_GetError());
