dealing with deffective RAM

Both Memtest86 and Memtest86+ find some failures in
RAM (one finds 11 faults, the other 14 - most 32-bit,
but some are only 8-bit wide). How can I deal with
this in FreeBSD? Buying new RAM modules is probably
the best choice, but I have no guarantee that the new
modules will be perfectly ok, so it might be wasted
money. Under Linux, I used the badram patch
(http://rick.vanrein.org/linux/badram/). Is there
similar functionality in the FreeBSD kernel, or is
there such a patch? I failed to find anything on
Google, and boot(8) didn't help much, either.
In case such a patch doesn't exist, do you have any
ideas about how such a thing might be implemented?
Eventually, could you point me to the right place in
the kernel source? I use Linux since 1997, but I'm
pretty much a FreeBSD newbie, so please be merciful...
P.S. I assume the physical pages (4k/4M) where the
faults reside could just be not mapped at all in the
virtual memory manager, so it should be doable, right?
