I am guessing this may be because you are relying on some shader effect
that is not suppoorted by my video card. This is a Thinkpad X200 with an
integrated Intel card. I know it is kindof a crappy card, but it is a
pretty common one.

You're right. The problem is probably the Intel GMA card.

According to thinkwiki you have the Intel GMA 4500 MHD, right?

My Thinkpad has the same gpu as fallback. That means that I should be able to
reproduce your problems. 

I will try to create a patch for Intel cards..

Ookay.

I could reproduce the problem.

I created a stripped down version that should work with your laptop. You can 
get the
tarball on the downloads page.

These are the differences to the normal version:
No particles - Needs geometry shaders.
No animated ponies - I do animation in the vertex shader. This doesn't seem to 
work
with Intel GPUs. I deactivated it for now. Maybe I will add a CPU fallback 
later.
No sand - The island is now completely grass, both over water and below. Seems 
like
multitexturing+shaders do not work.
The terrain has a lower resolution - For better performance.

I tried again with the current git version and I still get the same fail. Is 
there
something special I need to do in order to compile the stripped down version 
that
works on Intel cards?

...or maybe I am not getting the current version correctly. I did "git pull" 
but I
don't know if that is correct. I am pretty new to git.

You need the pink-pony_intel-1.0.tar.bz2 tarball from the downloads section.

What about the source code? Is there a git branch for the intel version?

It's a source tarball.
