Yeah, these are just symptoms of the X driver not handling the failure
condition as gracefully as it could. They're harmless.
Now, it's odd that there isn't anything pertaining to your AGP bridge in
the kernel output, and that lsmod shows intel_agp being unused. In my
experience, intel_agp should generate output about the hardware it
detects, and agpgart should increase the use count of intel_agp. What
happens if you unload and reload intel_agp?
At any rate, this looks like a kernel AGP issue rather than an X driver
issue.
