Sorry for false alarm - it was configuration problem :( (no "Modes" line for my default depth)
Now X starts, at 24bpp. twm and xterm are ok, gtk2 app (gqview) show some green rectangles under all it's text/icons in menus and toolbars. But at least X starts now.
Anyway, i will try xserver-1.6 just because long-unused things tend to broke.
