Yes, this module has not been updated for kernel 2.4.0 :-). Try
conditionalizing the init_module function in salf.c to only be present for
2.3 and up, i.e.

#ifdef LINUX_VERSION_CODE < 0x23000
int
init_module(void)
{
    if (safl_debug)
        printk(KERN_INFO "%s", version);
    return safl_scan();
}
#else
module_init( safl_scan() )
#endif

If you do get it working, please try and send us all the changes you made!
