dmesg.log after X has come up using drm.debug=0x7

The screen is blank before and after X is started when using KMS.  The display
comes up by disabling KMS with the "nomodeset" option. 

System environment:
Intel 845G
3.3.4-5.fc17.i686

I installed intel-gpu-tools-2.20.16-1.fc17.i686 but was unable to run
intel_reg_dumper. 

# intel_reg_dumper
Gen2/3 Ranges are not supported. Please use unsafe access.Aborted (core dumped)
