nvidia (GPU) panic and BOOT_COMCONSOLE_SPEED not working anymore

Hello,

I'd like to report a panic I get when loading the nvidia (GPU) module with 
a kernel with debug features invariants and witness enabled.

The it seems that the BOOT_COMCONSOLE_SPEED doesn't work for the kernel 
anymore, the boot bits respect that setting, but kernel console is always 
9600. Also setting machdep.conspeed in /boot/loader.conf doesn't change 
the console speed.

Thanks,

-Harry
