Uncomment the files.i386 line that adds k6_mem.c back to the build and it
will be reactivated.  The problem is that it's been implicated as causing
severe kernel (malloc and zone allocator) corruption when it's actually
used, eg: when firing up XFree86 3.9.16.  The code is quite harmless when
it's dormant though :-), but whem XFree86 4.0 gets released, it will cause
RELENG_3 machines to die all over the place, which we don't need.
