Ok. With the first modeline that you suggested it works fine, but it is really
more mensurable for eyes to work with 100Hz refresh rate on CRT monitor, so I
tried to generate new modelines (modeline from my xorg.conf with working form
me for years without any problems) with cvt and gtf:

# 1024x768 99.97 Hz (CVT) hsync: 81.58 kHz; pclk: 112.25 MHz
Modeline "1024x768_100.00cvt"  112.25  1024 1096 1200 1376  768 771 775 816
-hsync +vsync
# 1024x768 @ 100.00 Hz (GTF) hsync: 81.40 kHz; pclk: 113.31 MHz
Modeline "1024x768_100.00gtf"  113.31  1024 1096 1208 1392  768 769 772 814 
-HSync +Vsync

Both producing same distortion as I described in my initial post. Then I
switched back to your modeline ("1024x768_85.00cvt") to get good screen and
then tried to switch to 800x600 mode with systemsettings from kde4 (it's really
annoying to restart X every time, moreover it is refuses to start after two
restarts and I have to reboot my computer).

In 800x600 mode screen is also distorted. Here is a modeline from xvidtune:
"800x600"      56.30    800  832  896 1048    600  601  604  631 +hsync +vsync

After switching back to 1024x768 at 85 it works fine again.

P.S. I'm sure that my monitor and videocard is fine as it was working fine in
1024x768 at 100 mode for years in Linux and still working fine in this mode in
Windows. So it's really desirable to get back 1024x768 at 100 in Linux.
