It seems that these are the exact files I use. Somebody posted them on 
the groff Wiki too.

    http://www.port.de/cgi-bin/groff/KoiToPS

I also tested my example with the files in that archive you posted in 
the list.

Here are the map files which I fed to tfmtodit when extracting font 
files from cmcyr and AMS Fonts. Please, note that cmcyr has a bug in all 
italic fonts: cyrillic letter `yo' is missing. That's why when the need 
is to use italic font, I replace it with the AMS Fonts wncyi (Cyrillic, 
University of Washington).

Archive file cyrams.tar.gz contains:

    cmcyrmap           - Computer Modern Cyrillic map file;
    wncyrmap           - AMS Fonts Cyrillic map file;
    Makefile.cmcyr     - makefile for cmcyr font files;
    Makefile.amsfonts  - makefile for AMS Fonts Cyrillic font files.

AMS Fonts Cyrillic map file contains mappings only for glyphs found in 
KOI8-R character set, `Numero' sign used in cyrillic typography and 
guillemots. These are the only characters supported by cmcyr package.

To be consistent, I adopted the following convention for font naming:

- each font name originating from cmcyr is prefixed with `C'. For 
example, TR font is supplemented by CTR font, TI font is supplemented by 
CTI font and so on.

- each font name originating from AMS Fonts Cyrillic preserves it's 
original name, but converted to uppercase. For example, wncyr, wncyb, 
wncyi, wncysc and wncyss become correspondingly WNCYR, WNCYB, WNCYI, 
WNCYSC and WNCYSS.

To build font file descriptions I provide makefiles. Using them is 
simple. One can modify them for his own needs.

 $ make -f Makefile.amsfonts download

This will download ZIP-package, if you have no AMS Fonts, and unpack it.

 $ make -f Makefile.amsfonts

This will create font files, all with WNCY* prefix.

Same for the cmcyr font:

 $ make -f Makefile.cmcyr download
 $ make -f Makefile.cmcyr

Then simply copy uppercase font files to font/devdvi/ directory.

To be able to use cyrillic fonts with DVI backend, I declare them as 
special for a specific font using .fspecial directive:

.fspecial TR CTR
.fspecial TB CTB

for italic, however, I use AMS font wncyi, because it has letter `yo', 
missed in cmcyr italic fonts:

.fspecial TI WNCYI

Knowing that, I tried to change some settings and even exclude dvi.tmac 
file completely, but it brought no positive results. I attach my example 
file `hyph.roff' which I run with

 $ iconv -f utf8 -t koi8-r hyph.roff | preconv -e KOI8-R | \
 groff -mru -Tdvi > hyph.dvi

This example works with hyphenation when I request PostScript output

 $ iconv -f utf8 -t koi8-r hyph.roff | preconv -e KOI8-R | \
 groff -mru -Tps > hyph.ps

Thanks in advance.
