Hi, Michel.

Things are working better.

I agree.  I do not see a difference with these settings now.
In fact, I just put AGPMode back to 4 and removed SWCursor.
Now that I am using xorg unstable, I can only reproduce the
original shaking problem intermittently.

Quite correct!  I was using the etch xutils-dev, upgrading to the
unstable xutils-dev solved the macro problem.

My mistake.  I was using the Etch x11proto-core-dev.  Upgrade fixed the
CARD64 definition.

Thanks for the hints: I also upgraded to the unstable libgl1-mesa-*
packages and now even armagetron works fine!

Overall, everything is useable again after upgrading to xorg unstable.
