Well, looking at the latest Xorg.log it seems that the nv driver works as
intended.  The basic problem is that the driver can't find a suitable value for
hsync and vrefresh and, as a result, has to abort.
Looking at the values in stack 12 in post 20 it's obvious that the hsync and
vrefresh values are ridiculously small.
Apparently you don't have a xorg.conf with a Monitor section and the driver is
making a wild guess about the suitable clocks.
If you have the hsync and vrefresh information for your screen then you should
definitely add a Monitor section!
As an example, this is what I have in my xorg.conf:

Section "Monitor"
Identifier      "BenQ"
HorizSync       31.5 - 82.0
VertRefresh     50.0 - 90.0
EndSection

Section "Device"
    Identifier     "GeForce1050Ti"
    Driver         "nvidia"
EndSection

Section "Screen"
    Identifier     "Screen 1"
    Device         "GeForce1050Ti"
    Monitor        "BenQ"
    DefaultDepth    24
EndSection
