Bug #400 (partial): Driver fixes for the dlloader. When using dlloader, all

    framebuffer formats except cfb and the overlay modes should work, and
    r128 and radeon need to be loaded from the ati driver (both issues to
    be fixed soon). Tested on i740, s3virge, mach64, tdfx, vesa, and vga
    drivers. elfloader users shouldn't be affected.
