I believe the policy used in this config file (i386/conf/GENERIC) is
that compatibilities are provided by loading 'compat' module, since
rev. 1.918.  And as I described above, enabling *only* COMPAT_50
prevents the 'compat' module from successful loading, and as a result,
all other compatibilities like COMPAT_30 etc aren't available with
this GENERIC kernel.
