This looks like a similar problem I found. Try to edit 
        /sys/i386/boot/biosboot/boot.c
Look for this line: for(ret = 0; ret < N_BIOS_GEOM; ret ++)
Replace N_BIOS_GEOM by 3 (which is the number of devices you have
on you hd controllers).
Then type 
        make
        make install
        cd /usr/mdec
        disklabel -B wd0
  
If I'm correct, this would solve the fact that FreeBSD does not 
automatically boots from wd(0,a)/kernel.

Could you report back to this list if this fixes it?
