I think you have to mount the debug filesystem [1].

PS: Maybe that and the i915_error_state stuff could be added to the
Intel Web site too [2].

PPS: Angela, you can also join the IRC channel #intel-gfx for live
debugging.

PPPS: Angela, can you use a different mail program which can quote
correctly. Outlook should be able to do it, but I do not know how to
configure it. Thunderbird works under Microsoft Windows.
