I have installed and booted a vanilla 2.6.21.1 kernel,
but this does not seem to change anything.

The lockup is quite reproducible: I start the molecular
visualisation program PyMOL (which uses Tcl/Tk, Python and
OpenGL) and open a menu to start a demonstration which
shows a number of rotating objects. This works fine,
but when I try to open the menu again, the server
locks up.
