DIMM population information

[Chris Ross <cross+netbsd%distal.com@localhost>]

  Is there a way to see, when running NetBSD, what DIMM slots are populated, 
and with what size of DIMM?  In my case, I'm most interested in a Netra X1, but 
I also have a e420r and a v240, so what may work on one may or may not work on 
many.  But.

  I looked at the output from ofctl, but didn't see this specific information 
in there.

  Is this something that's available?
