LCD monitors / ADD Cards / Motherboards with DVI-D interface --Support in *BSD

[Constantine]

Hello,

I have a FreeBSD system running on AOpen AX4G-N motherboard with Intel 
845G(+ICH4) chipset. I don't yet have any monitor on the system and I 
have very little experience with configuring and running X on UNIX 
systems, and I have never configured X with LCD monitors.

I'm considering buying an LCD monitor, presumably IBM L170p.

I am still looking for the hardware with the DVI support. I found that 
probably what I want is the ADD Card (AGP Digital Display Card), but I 
have problems locating resellers for that card, so any help is welcome 
(one example of such card is here: 
<http://usa.aopen.com/products/mb/add.htm>). I reside in the United States.

What problems am I likely to experience with the configuration of the 
graphics card and LCD monitor in FreeBSD and/or OpenBSD? I'd really like 
to have a clear, crisp picture on the new system, no matter if I am 
going to use it as a console or a GUI system. If you have any advices or 
good links, let me know.

Thank you,
Constantine. :-)
