X log file

Upon swapping video cards, I have started getting intermittent freezes of X
on my Slackware65 13.37 AMD Opteron box (kernel 3.4.4)

The display freezes up totally, including mouse pointer; occasionally there are
short (eg ~10s) freezes which might be related, and usually it happens when
web browsing (mostly when there is embedded flash on the bbc.co.uk olympics
pages) 

I hope the below is sufficient info; I need to swap video cards back because I
can't afford such lockups ATM.


Here's the lspci lines:

This appears in /var/log/messages (if I wait 20+mins, it seems to unfreeze
fairly reliably)

There is no error logged by X, but here its (but note that I run 6
