I gave up on waiting and just pushed my original fix.

i965: Don't enable reset notification support on Gen4-5.
arekm reported that using Chrome with GPU acceleration enabled on GM45
triggered the hw_ctx != NULL assertion in brw_get_graphics_reset_status.
We definitely do not want to advertise reset notification support on
Gen4-5 systems, since it needs hardware contexts, and we never even
request a hardware context on those systems.

Hopefully it'll get picked up for the next 10.1 release...
