Interlaced mode

Hello,
I want to know if my notebook (Dell Latitude Cpi) with NM2160 is capable of
use interlaced screen mode on external monitor. I've tested VGA to SCART
convertor which works fine with my home computer, but not with notebook in
resolutions, which uses interlaced mode. Also OSD on my monitor reports with
this modeline

Modeline "720x576i"   27.00  702 722 785 864  576 580 584 625
interlace -hsync -vsync

30.3 kHz vertical refresh and 48.8 horizontal, which means dot clock about
26.0 MHz (it seems not to be fluently programmable). On my home computer
with same modeline reports 31,3 kHz and 100 Hz, which corresponds better to
modeline.

  Thank you, Petr Hlavka.
