I assume you added these variables to either the GENERIC or a custom
kernel in /usr/src/sys/i386/conf. If you created a custom kernel called
CUSTOM, then you would:

cd /usr/src
make buildkernel KERNCONF=CUSTOM
make installkernel KERNCONF=CUSTOM

Just wanted to verify that you built and installed the kernel using the
config file that has the settings you listed above (your sysctl output
would indicate otherwise).
