The work around is to manually set up your monitor after the install. Which, in case you don't know, means editing your etc/X11/xorg.conf. I don't have a reference here, but search for "xorg.conf" manual pages. You need to add a "Monitor" subsection for your monitor, then update your "Screen" subsection to know about that monitor. You set your refresh range in the "Screen" section if I recall. This is a fairly common problem I think.
