crash with ATI Radeon X1900 XT and second HD display (DVI) ?

hi ! i have a realy tough one for you guys : since 3-4 days i've been getting this realy strange (and scary!) kernal panic screen / crashes / freeze with my macpro dual 2.66 with ati radeon X1900 xt.

the crashes keep coming while doing extensive work (video converting, renders) or just letting the macpro running doing nothing much all night long...

now this is what i found for now : if i disconect my 2nd display (samsung syncmaster 2493hm HD in DVI 1080p) it seem to be stable. when i reconnect it sometime it can run again with this 2nd display for a while but when i leave a render all night long the next morning it will be frozen, nothing on screen (all black).

after rebooting it get this crash report from the system :
