If you put
options COMPAT_LINUX
in your kernel config file, Linux compatibility is already enabled and not
shown in the list of loaded kernel modules! kldstat only reports thos 
modules
are enabled as loadable module.
With "options COMPAT_LINUX' Linuxulator is enabled forever as long as 
the kernel runs.
A more sphisticated way is to run Linuxulator as a kernel loadable 
module. You should disable
options COMAPT_LINUX in your configuration file and change the 
appropriate tag in /etc/rc.conf.local

linux_enable="NO" -> linux_enable="YES".
