If you use the /etc/init.d/microcode_ctl runscript and have
MICROCODE_UNLOAD="yes" set in /etc/conf.d/microcode_ctl (which is the
default), it will unload the module automatically after it runs, so
you shouldn't see it in lsmod anyway, and saves a few kb of memory.
But, quite honestly, 8kb of memory is probably inconsequential on a
system where microcode_ctl is being used in the first place... :)
