Here is the lspci output showing the graphics card:

$ lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI 
Cedar PRO [Radeon HD 5450/6350]

My post prior to the one you quoted above has the entire contents of 
both logs.  After posting them, I saw where the logs diverged so 
radically and made another post with just the excerpts.
