Did you have something like the patch below in mind?  (Not committed
yet.)

BTW, I cannot believe that even with FreeBSD 6.2 we still need to hack 
/boot/loader.conf and reboot to support more than 512MB per process. Is
there really no better way?  I failed to find suitable documentation on 
FreeBSD.org so far.
