Yes, you should try that. The environment variable doesn't affect X, it
affects the 3D driver that is loaded when you start Terminus. BTW, I
could try to download a Terminus Demo tomorrow. Do you have a link for a
download. I havn't found a Linux Demo download with Google yet.

This is just the result of wait_event failure in the kernel.

If you don't know about driconf you should definitely check it out
(http://dri.freedesktop.org/wiki/DriConf). It lets you browse a number
of driver-specific options and allows to change them on a
per-application level. They are saved in a configuration file that is
evaluated by the 3D driver. You may want to experiment with other
options (for example texture heaps or the fast path). If any one of them
makes a difference it would be interesting for me to know.
