This does fix the "No per-cpu room for modules" error, but we then go back 
to the "module ipv6: Relocation overflow vs section 27" error, as seen in
http://archives.neohapsis.com/archives/linux/axp/2005-q1/0157.html and as 
early as 2.5.72: http://lkml.org/lkml/2003/6/24/64

There's a patch at http://lkml.org/lkml/2004/1/11/42, but that's already 
been applied. http://lkml.org/lkml/2004/1/8/99 suggests it might be a gcc 
issue - I'm using gcc (GCC) 4.1.2 20061028 (prerelease) (Debian 4.1.1-19).
