I'm beginning to wonder if removing ACPI and/or AGP solves the problem  
myself.

I shutdown and restarted XFree86 over 20 times with both ACPI and AGP.   
I was beginning to think it was fixed... then it froze up right when my  
confidence was high! :|

So it seems very unpredictable on my system at least.

I've never loaded agp as a module.  I've either built the kernel with  
or without agp support.  I've also built the kernel with and without  
radeondrm - no apparent difference.

This may be the same thing mentioned on (under Todo):

Currently I don't seem to be having the problem very often... which is  
strange.  It's like my system was just having a bad day or  
something! ;)
