Reboot Hangs

[Doug Hardie]

FreeBSD 5.3-P5 with options        BROKEN_KEYBOARD_RESET in the kernel.

System was first built on hardware that required that option to be able 
to avoid hanging on reboot.  However, now I have installed it on a 
newer system.  It still has the option defined.  And it hangs.  I 
suspect that I don't need the option on this system.  Is there a way to 
disable it without having to rebuild the system?
