It is not sufficient to just add that resolution to seabios list.
I mean, it is not only bios which should have support for it.

For example, qemu/kvm will not work with it.

The problem here is that 1366 is not dividable by 8.  In other words,
each line on the screen does not end at a byte boundary in memory.
This is a very weird resolution.  Most devices which actually implement
it use 1368x768 and just crop two vertical one-pixe-wide lines on both

This does not look real.  Being a very weird resolution, with very
few devices available in stores all around, it can't be real.

But even if it _is_ real, it does not make this resolution any
less weird.


/mjt, who added it once to seabios (not a rocket science to add 3 lines
      to vgasrc.c) just to discover that qemu crashes once (windows)
      guest tries to switch to it
