According to my searching via google, this looks to be about the current
status of this board.

If the above DRAM memory search range is a custom that is related to
this specific Tyan S1832DL, how about I provide an svn diff for
inclusion into the tree?  (If not, will just keep using s1846 tree and
is preferable for further code updates.)
