You can set it in KERNEL by disabling 32 bit application support and recompiling GLIBC and GCC without MULTILIB ;). Try also running 32 bit app. System is not slower or anything else wrong happens. If You drop 32-bit support You cannot use WINE and load PE32 apps (aka Win32). -- Mateusz Mierzwiński Bluebox Software
