If I understand the process correctly, settings in /boot/loader.conf 
override settings in /boot.config as the boot loader happens after the 
boot blocks.  Thus by setting "comconsole" will negate any settings in 
/boot.config.  Setting in both places is redundant and may cause 
problems for you when troubleshooting.

For my serial console, I set my kernel flag to 0x10 so I have console 
options without recompiling.  Then I do my serial console settings in 
/boot.config as it happens earlier in the boot stage and thus, I get my 
serial console a little sooner.
