Hi !
Following fixes problem with MOD_UNLOAD for syscalls (more serious, as I
think) (now kern_syscalls.c:syscall_module_handler() will be very close to
kern_conf.c:[bc]devsw_module_handler(), which was already patched for
the same reasons :) Patch produced for v 1.3 of kern_syscalls.c

But what about kern_module.c:module_register_init() and
kern_linker.c:linker_file_sysinit() , which still void in both -stable and
-current ?
