I have another example of this bug with a different monitor: a Dell SP2309W.
Another Dell if that is significant.
The SP2309W has a native resolution of 2048x1152 and nv gets that right when a
VGA
cable is used:

======================================================================================
It looks as if the EDID block is being read correctly if I understand
http://en.wikipedia.org/wiki/Extended_display_identification_data .
At least the only difference looks like byte 20 which is presumably
just noting the difference between the VGA and DVI signals. But I have not
checked properly.
Why should the nv driver interpret the tiiming data differently for different
interfaces?
In passing, it seems that the closed source nvidia driver also has problems
with this monitor on DVI-D. Is Dell doing something evil in its monitors?
