This, along with the follow-ups, reminds me of a problem I had with a
Dell Inspiron 5100 some years ago.  In that case, X didn't map the
video BIOS correctly, and so it wasn't able to read the information
from the BIOS.  The information includes things like the panel
geometry, which in my case was being reported as 65535x65535 pixels.
In your case we have:

That's clearly wrong too.


It's equal to the values in the
documentation<http://support.euro.dell.com/support/edocs/systems/latd610/en/ug_en/specs.htm>,
rounded off to integers.

See
http://www.lemis.com/grog/diary-jul2003.html#25 for more details.
It's worth mentioning that the problem was fixed in a later version of
the system, and I can now install X on it with no problems.

If this looks familiar, a couple  of suggestions:

1: Try XFree86.  Maybe that will work better.


I'm a bit reluctant to straying away from the recommended setup on my work
machine. Besides, isn't the code base for this and X.org still very similar?

2: Get hold of the latest Knoppix CD and see if that works.  If it
   does, it might help fix the problem under FreeBSD.


Do you mean running
Xorg -configure
and see if it gives the right information? If not, could you elaborate a
bit? Thanks!


3: Use the method I described in my diary to build a server with a
   static version of the video BIOS.


I'm not a C hacker, so I think this is a bit too far off.
