Bug#692092: I believe I found the cause of the problem.
I reported this bug, one thing I noticed was this,
This machine only has an AGP aperature of 8MB in the bios, I know, I
set it, but this software clearly thinks it has 128mb available, this
might be the cause of the hung gpu? , anyone know, im not a software
expert, but thats my theory.
Hope some developer sees this and it proves useful.
