If the thing acts like a plug-and-play monitor, then just maybe, read-edid
might work:

(this is what I reached after redirect when following the link in its docs)
This is a really weird package though; it was only available as source,
and even when that's compiled, you run 'make read-edid' while root (so you
can ask the display) and it will try to cook up some modelines for you.
Hasn't caused me problems, but hasn't worked on every monitor, either.

I haven't used really low pixel-res like that on a laptop, so I have no
idea, sorry.
