I think this has always been possible OOTB with xdvi, provided that
you activate src-specials when producing the dvi.

Only a wrapper is necessary. I attach here an excerpt of the README
file in the LyX/Cygwin package, explaining everything.

What do you mean? When using xdvi you only have to be sure that
src-specials are activated and then you simply Ctrl-click in the
xdvi window to jump to the right location in the LyX window.

Reverse DVI search
------------------
Reverse DVI search allows the cursor in LyX to automatically jump to the
point corresponding to where you Ctrl-click (if using xdvi) or double click
(if using yap) in the previewed DVI file.
This feature can be enabled as follows:
* Activate src-specials by changing the "LaTeX (plain)->DraftDVI" converter
in Tools->Preferences->File Handling->Converters to "latex --src $$i"
if you use tetex, or to "latex -src-specials $$i" if you use miktex.
As an alternative to redefining the converter (maybe because you use
pplatex instead of latex for producing a DraftDVI), you can insert
"\usepackage[active]{srcltx}" in the preamble of the LyX file.
* A program or script will be called by the dvi viewer when initiating
a reverse dvi search (xdvi uses Ctrl-click, yap uses double click).
This program should take 2 arguments, a filename and a line number, and
should pass this info to a running instance of LyX. This can be done
either using the lyxpipe (set by default to ~/.lyx/lyxpipe) or the
unix domain socket that lyx creates in its temporary directory.
A suitable script (/usr/local/bin/lyxeditor.sh) is already included in
this package for using the lyxpipe machinery. You could modify it in order
to better fit your needs, but it should already work out of the box.
Alternatively, you can use lyxclient.exe for communicating with lyx
through the socket mechanism.
* If you use xdvi, you don't need to do anything else, as lyx already
provides the necessary hooks for automatically using lyxclient.exe.
However, if for whatever reason you want to use the lyxpipe instead
of the socket for communicating with lyx, simply change the DVI
viewer in "Tools->Preferences->File Handling->File formats" to
"xdvi -editor 'lyxeditor.sh %f %l'" (without double quotes), where
lyxeditor.sh is the aforementioned script.
* If you use yap, you should set the name of the program directly in yap
through the View->Options menu. However, as yap is a native Windows
application, both lyxeditor.sh and lyxclient.exe have to be launched
through the wrapper program /usr/local/bin/lyxeditor.exe (after
installation, you will find its source in the /usr/local/share/lyx/etc
directory). After launching yap, choose the View->Options menu and select
the "Inverse DVI Search" tab. Click on the "New..." button and, in the
window which opens, enter "LyX Editor" (or any other name you like) in
the "Name:" field. Now click on the button labeled "..." to open a
filedialog and navigate to the directory containing lyxeditor.exe (it
will be C:\cygwin\usr\local\bin if C:\cygwin is your root directory).
Select lyxeditor.exe and then specify the program arguments as "%f %l"
(without the double quotes) if you want to use the lyxpipe, or as
"-g %f %l" (again, without quotes) if you want to use the lyxsocket.
* If you did no mistakes, and if src-specials are activated as previously
described, whenever you Ctrl-click in xdvi, or double click in yap, the
cursor in LyX should jump to the desired location.
