No, alt + sys + k and b don't work

I found an even better one : glxgears makes the freeze after only 1 minute !

I also have a 2.6.19-rc3 kernel and it freezes likewise. My feeling is
that it even freezes faster with this one but it's probably no more than
a feeling.

direct rendering: Yes

It doesn't seem to happen after several minutes running glxgears.
Disabling dri allows me to play crack-attack, that's already a good point :)

SSH from another computer doesn't work either
