Yes, it's just trivial.
Pretty much any laptop made in the last five years can handle virtual
size up to 2048 wide. Many can go even further. Anything with DVI or
HDMI can drive 1920x1200 [1]. If the 19x12 display is connected at
server startup, we'll even size the virtual big enough for you. If it's
not it might take a little coercing.
Section "Screen"
Identifier "Screen0"
# ...
Virtual 1920 1200
EndSection
Will force the virtual size to 1920x1200. Prior to xserver 1.6, RANDR
1.2-style drivers would not give you the traditional panning view within
that virtual size; as of xserver 1.6 that's possible but requires that
it's been wired up in the driver.

have enough.
