It's possible that your xorg.conf is messing you up---I bet you it's a
remnant of the old setup, and quite possibly not necessary. The long
list of modelines was how I learned to do X11 back in the days when we
had to whittle ones and zeros out of oak timbers but nowadays,
xorg.conf is just few lines long, and the Xorg server finds out the
video hardware, reads the monitor parameters over the video cable and
matches it to the built-in list of VESA standard modes. It'd be
interesting to try with a virgin minimalistic xorg.conf
Section "Device"
Identifier "Videocard0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
EndSection
and maybe it'll figure something out on its own. I don't know if
1360x768 is on the VESA list so maybe you do need it after all.

It has to match the "Monitor" section your Screen section is using;
there could be multiple Monitor sections
("Monitor1","myOldCRT","LCDmonitor2", etc). Say something like
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "MyMonitor"
...
Section "Monitor"
Identifier "MyMonitor"
Modeline .....
...

Nope, I doubt it, every VGA card is capable of any resolution from
like 320x320 (?) to 8000x8000 (???) within the memory capabilities and
video clock speed; the limitations come from the monitor and driver
limitations.

I will bet you a beer that your card is capable of driving your
monitor resolution.
