The code in question (LiS) is LGPL and open source. The iBCS packge is GPL and open source.
You do know that there *is* open source code which is not contained in the Linux kernel ;)
So, in this case, GPL and LGPL modules do have a problem linking with the sys_call_table (on RH 8.0 and I suppose some development kernels only), because the symbol is no longer exported and no registration procedure was provided for registering otherwise non-implemented system calls (in particular the UNIX98 and iBCS/ABI standard putmsg/getmsg calls).
And what about AFS? I see that it uses a sys_ni_syscall slot as well...
In fact all these components are opensource.
