Hi,
svgalib needs to be compiled without background support in order to run under kernl 2.4.0 or newer. Here's a patch to Documentation/Changes that says this.

+SVGAlib +======= +If you want svgalib programs to run with kernel 2.4.0 or newer, svgalib +needs to be compiled without background support (BACKGROUND not defined in +Makefile.cfg). This is relevant to any svgalib version. +This is because svgalib uses mmap of /proc/mem to emulate vga's memory bank +switching when in background, and kernel 2.4.0 stopped supporting this feature. +
