I think I am almost there, but in my case, I get some strange char 
duplication after seeing the F1 prompt. The BIOS has console 
redirection, so I can see it throughout the bootup process.

F1   FreeBSD

Default: F1

FreeBSD/i386 bootstrap loader, Revision 1.1

If for some reason, boot.config is bogus, I can actually type in 
/boot/loader and it will load, just what I type is duplicated.

I have

# cat /boot/loader.conf
beastie_disable="YES"           # Turn the beastie boot menu on and off


# cat /boot.config
-Dh -S19200

After hitting enter as I normally do, the rest of the boot process is 
normal looking and works fine
