Subject:   PXE (pxeboot) and serial consoles - force it!

I'm playing with PXE and pxeboot.   I have a question about
setting the serial console option.  The PC BIOS reports 
'No Keyboard Present', but when PXE boots, BTX reports
console as internal keyboard/video.  So, I'm looking at
hard coding a serial console into BTX.  Normally, you
put the -h option into /boot.conf, but PXE doesn't
read that.  I tried putting console=comconsole into
/boot/loader.rc, but it didn't work quite right.
I modified src/sys/boot/i386/common/conf.c and
removed the vidconsole option and that worked.
I could set the flags in the kernel to 0x20 to
force serial and that worked.

I'd like a more 'supported' option.  That allowed
me access to BTX before booting the kernel.  Does
anyone have a suggestion?  Is there a /etc/make.conf
option I could set?  

Thanks.
