Rather than a configuration of the type you're familiar with, I'll bet the
newer way will work, if not with your custom installed system, at least with
a common recent live media distro as a means of proving. Modern Xorg automagic
should get the whole job done, up until the point of panning configuration, if
instead of VESA, using the newer technology default DDX driver provided by the
XServer rather than in a separate package.
Start by eliminating 20-vesa.conf, 40-samsung.conf and 90-screen.conf from
xorg.conf.d/. Let X startup in the Samsung's native 1280x1024 mode using the
default "modesetting" DDX. Then try as follows:
# xrandr | head
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 8192 x 8192
DVI-I-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis)
338mm x 270mm
1280x1024 60.02*+ 75.02
1280x960 60.00
1152x864 75.00
1024x768 60.04 75.03 70.07 60.00
960x720 60.00...
# xrandr --fb 1280x1280 --output DVI-I-1 --mode 1024x768 --panning 1280x1280
# xrandr | head
Screen 0: minimum 320 x 200, current 1280 x 1280, maximum 8192 x 8192
DVI-I-1 connected 1280x1280+0+0 (normal left inverted right x axis y axis)
338mm x 270mm panning 1280x1280+0+0
1280x1024 60.02 + 75.02
1280x960 60.00
1152x864 75.00
1024x768 60.04 75.03* 70.07 60.00
960x720 60.00...

I used nearly the same kernel and XServer as yours, as well as an NVidia GPU
not terribly newer, and a Dell LCD. I do have a 1280x1024 Samsung SyncMaster
914V, but it's upstairs, and has no DVI port, so more bother to test with.
Ignore what you see about the XGI GPU. This Gigabyte's BIOS doesn't understand
how to do it's job correctly when a PCI GeForce is installed.
If it works as I expect, you can put xrandr in whatever script you start
X with, or another. If it fails, I'd like to see the resulting Xorg.0.logs
from both your custom build and any recent live distro that depends fully
on automagic X configuration.
Be sure you do not have the Xorg nouveau DDX installed, as it will usurp the
modesetting DDX, unless you perform additional manual configuration.
