#57 Unable to get suitable monitor resolution on VT3108.

[Aleksey]

Without any ModeLine options on xorg.conf via-unichrome
driver will use maximum resolution at 1600x1200 on my
monitor (Samsung SyncMaster 795DF).

I used xf86-video-unichrome-0.2.3.tar.gz to build a via
driver and ModeLines from
http://kudos.berlios.de/kf/vesaire/modes.txt to force
driver to choose lower resolution (like 1024x768). But
still 1024x768 is the only resolution what work even
with ModeLine options. But monitor always shows
64.6k/80 NN refresh rate.

Any chance to get it worked atleast at 85kHz?

What I need to change on ModeLine's or any glue?
