Latest -current, but missing in 2.1.0-RELEASE as well.

>Description:

There have been several postings to -questions recently from people
asking why FreeBSD can only see 64MB when their machine has more
RAM. This should IMHO be in LINT, especially as such machines are
likely to become more and more popular.
